| + | The geology of Chengdu has a long history and the stratigraphic exposure is relatively complete. The hypsography of Chengdu slants gradually from northwest to southeast. Characterized by hills and gullies is the western peripheral area of [[Sichuan Basin]], which is 1,000 -3,000 above the sea level. The highest part is [[Shuanghe]] (Twin rivers) located in [[Dayi]] county with an altitude of 5,364 meters and a relative altitude of 1000 meters. At the bottom of Sichuan basin is the eastern part of Chengdu, forming the heartland of Chengdu plain. It is mainly composed of alluvion plains, mesas and part of low hills, where there the land is profound and fertile. The lowest part of the basin is only 387 meters, which located in [[Yutai]], [[Jintang]] County. Due to the great difference of 4,977 meters on altitude between the east and the west of Chengdu, the moisture and heat distribution varies quite remarkably. As a result, in the mountainous areas of the west areas, the temperatures of air, water and land are much lower than that of the eastern plain. Moreover, even in the same mountain, the vertical distributions of different climatic zones occur. As a result, large varieties of vegetations grow in profusion, which provides favorable conditions for the development of agriculture and tourism for Chengdu. |

| − | == History of Chengdu ==
| |
| − | | |
| − | With it's long history of over 2,300 years, Chengdu was proclaimed one of the 24 cultural and historical cities by the [[State Council]] at the first batch.
| |
| − | Early in the 4th century BC, Kaiming IX, king of ancient Shu, moved the capital from Guangdu Fanxiang (now called Shuangliu) to Chengdu. "A town was built in this area in the first year and the capital in the second year, so the ancestor name the city as Chengdu, which means "became a capital" in Chinese.
| |
| − | | |
| − | In 311 B.C, people of [[Qin Dynasty]] (221 BC-208 BC) built a protective wall around Chengdu city according to the construction standard practiced in [[Xianyang]], capital of Qin Dynasty. Thus, the wall was erected with a height of 3.5 meters and a perimeter of 6 kilometers, marking the beginning of Chengdu City.
| |
| − | | |
| − | The [[Dujiangyan Irrigation System]] was constructed under the lead of [[Li Bing]], prefect of Shu Prefecture. The Dujiangyan brings the vast [[Chengdu Plain]] under irrigation and protects it against droughts and floods for over 2000 years. Chengdu plain was turned into the Land of Abundance with temperate climate and fertile soil. | |
| − | | |
| − | In [[Western Han Dynasty]] (206 BC- AD 23), brocades produced in Chengdu enjoyed good popularity in [[China]]. The government assigned [[Jinguan]] (an official in charge of brocade production) to administrate the brocade production in Chengdu and the Jinguan City was constructed. So Chengdu is also called Jinguan City or "Brocade City".
| |
| − | | |
| − | In the [[Five Kingdoms Period]] (907-960), [[Mengchang]], king of the Latter Shu Kingdom, decreed to plant hibiscuses on the protective wall of the city, so Chengdu is also called the City of Hibiscus.
| |
| − | | |
| − | Through the history, Chengdu was a city densely covered by rivers and dotted with bridges, while trees grew in profusion and flowers bloomed all year around. No wonder that a traveler from France in the 19th century praised Chengdu as Oriental Paris. Over 2,000 years, Chengdu has remained a city of military importance in Southwest China on politics, economy and military affairs. [[Gongsun Shu]], king of Western Han Dynasty, [[Liu Bei]], emperor of the [[Three Kingdoms]] and [[Meng Zhixiang]], King of the Latter Shu Kingdom all founded their capital in Chengdu. Later in the [[Yuan Dynasty]] (1279-1368), the [[Ming Dynasty]] (1368-1644) and the [[Qing Dynasty]] (1644-1911), it remained the location of government for Sichuan province. Early in Ming Dynasty (1912-1949), it was the capital city of Sichuan province. On December 27, 1949, Chengdu was liberated and chosen as the location for the administration office for Sichuan province. Since 1952, when Sichuan resumed its status as an administrative province, Chengdu became capital.
| |
| − | | |
| − | Chengdu has also been a city with prosperous industry and booming business activities. In the Qin Dynasty (221 BC-206 BC) and the [[Han Dynasty]] (206 BC-AD220), it was a well-known business center. In the Han Dynasty, it was one of the five best cities in China, the other four cities being [[Luoyang]], [[Handan]], [[Linzi]] and [[Wan]]. It ranked second, next only to [[Yangzhou]] in the [[Tang Dynasty]] (618-907), in the [[Northern Song Dynasty]] (960-1127), next only to the capital city, [[Bianjing]]. Early in Tang Dynasty and [[Song Dynasty]], the commerce and trade in Chengdu had outgrown the traditional family workshops, gradually developing into a modern city of sophistication. Each month was devoted to different fair: January for lamps, February flowers, March silkworms, April embroideries, May fans, June incense, July jewel wares, August sweet-scented osmanthus trees, September wines, October plum trees, and December peach wood charms. Besides, in the downtown areas, the markets for after-supper shopping began to flourish. Even to this day, names of some old streets testify to that history, including names like Yanshi Street (street for salt trade), location of city council, and business Street, location of branch office of [[Communist Party of China]] in Sichuan. Paper money appeared and was first used in [[China]], Chengdu being its birthplace. At that time, workshops for paper money making were located in [[Jingchong Temple]] to the north of Chengdu city (today known as Wan-fu Temple, [[Temple of Ten Thousand Buddhas]]). The paper money made here was the earliest paper money ever used, which played a significant role in promoting trade, financial transaction, and economic development.

| − | Chengdu also has the longest history for gas exploration and utilization. Early in the Western Han Dynasty (206 BC-AD 23), natural gas was discovered and used in salt-refinery. Li Bing, Magistrate of Sichuan province then, built canals to lead rivers to flow before Chengdu city, greatly improving its transportation. Soon later, merchants set out from Chengdu to embark on the long journey for silk trade known as the [[Silk Road]]. Chengdu has been proud of its great contribution to the culture of China as well as the world.

| − | With a long history, the education in Chengdu is well developed. Early in 141 B.C, [[Wen Weng]] built schools to promote education, which was the first attempt in China for public education. Till the [[Southern Song Dynasty]] (1127-1279), the school had grown into a college with an enrollment totaling 1,000 members. This may explain why Sichuan has been the birthplace of so many talents with the Western Han Dynasty (206 BC-AD 23) and the Eastern Han Dynasty (AD25-220 BC) as its prime time. Chengdu was a leading city in paper making in the [[Sui Dynasty]] (581-618 ) and in the Tang Dynasty (618-907) and he hemp paper made in Chengdu was officially prescribed for decree writing and the Central library of China at that time. Later, the wood block printing technology was another great contribution made by the Chinese people to the civilization of the whole world. Once again, Chengdu was among the first to introduce and adopt this technology. In the Song Dynasty (960 BC-1279 BC), Chengdu was one of the three printing centers, and its printing technology was honored as "the most advanced in China."

| − | Chengdu is also known for its handicrafts. From the Warring States (770 BC-476 BC) to the Han Dynasty (206 BC-AD 220), lacquer wares enjoyed a high popularity abroad. Hometown of the famous Shu brocade, Chengdu has been an important city for brocade weaving and the silk culture in China. In the Han Dynasty (220 BC- AD 206) and the [[Jin Dynasty]] (265-420), the colored silk from Sichuan was extremely popular in China. For a long period of time between the Six Kingdms and the Tang Dynasty (618-907), most of the silks exported to the Middle Asia were made in Chengdu. In 1909, the Shu colored silk won the first prize in the Southeast Asian Fair. In the Han Dynasty, the hemp cloth was the first-grade cloth, finding a ready market in countries as far as Afghanistan (known then as Daxia).

| − | In the Tang Dynasty and the Song Dynasty, [[Sichuan Opera]], with a large variety, dwarfed all other operas in China. Musical instrument was also famed. With a long history in making musical instruments, a family known as Lei amazed the world with their masterpiece. Also, wall paintings in [[Daci Temple]] (Temple of Great Mercy) were honored as "the Best Wall Painting in China."
| |
| − | | |
| − | Tea cooking and tea culture originated in Sichuan, China . And [[Xinjin]], a town of Chengdu, was the first to begin tea trade. Even in poetry, the earliest description about tea drinking was found in Chengdu. In the Tang Dynasty and the Song Dynasty, Chengdu remained an important base for tea production, and it was also an important center for tea trade, either for retailing or in wholesale. Since the Qing Dynasty (1644-1911), teahouses here gradually developed their own unique style which could be found today. Besides, Chengdu has the largest number of teahouses in the world.

| − | Chengdu has been an open place gathering talented minds. In the Han Dynasty when ''Fu'', a genre of literary creation, was extremely popular, there were four acknowledged masters in composing Fu, two of which were people of Chengdu, namely, [[Sima Xiangru]] and [[Yang Xiong]]. Later in the Tang Dynasty, [[Huan Quan[[ and his son, [[Huan Juchai]], were master painters. In the Song Dynasty, among the prestigious historians are two Chengdu people, namely [[Fan Zhen]] and [[Fan Zuyu]].

| − | Moreover, Chengdu was also the love of many personages, such as [[Zhuge Liang]], an outstanding statesman, and other poets including [[Li Bai]], [[Du Fu]], [[Cen Shen]], [[Xue Tao]], [[Wei Zhuang]], [[Lu You]] and [[Fang Cheng]]. Understandably, it was believed that Sichuan was of irresistible attraction to poets. Many other figures spent their schooling years in Chengdu, among which were [[Zhu De]] and [[Chen Yi]], the great proletarian revolutionists, [[Guo Moruo]], [[Ba Jin]], [[Li Jieren]], and [[Li Yimang]], writers of modern China, and [[Zhou Taixuan]], the scientist.

| − | The city has been characterized in cultural traits by non-exclusiveness, absorptiveness, enterprising and openness. The coming of Kai Ming people into Sichuan brought with themselves the Jing and Chu culture. Soon later, the unification of China by the Qin Kingdom introduced another new culture, added later by a new wave of immigration of merchants from all other six kingdoms, bringing in knowledge of business management and industry. On the other hand, Wen Weng, a great advocator and patron of education then, sent many of his students to the capital city for study. Later in the Sui Dynasty, [[Yang Xiou]], when designated to be governor of Sichuan, brought with him a group of master monks from China, thus making Sichuan an important center for Buddhist studies. [[Emperor Xuan Zhong]] and [[Emperor Xi Zhong]] of the Tang Dynasty made two imperial visits to Sichuan. Coming together with them were large groups of poets, painters, artists and talented minds of many other trades. In the Qing Dynasty, a large number of people from [[Hubei]] Province and [[Guangxi]] Province moved into Sichuan Province, which helped to promote the communication in economy, culture, and customs. By either assimilating or learning from other people and places, Chengdu gradually developed its own opera, namely Sichuan Opera, painting, [[Sichuan cuisine]] and snacks, all of which contributed to the formation of Chengdu culture. During the Eight-year Anti-Japanese War (1937-1945), many associations, societies and celebrities moved to Chengdu, added later by another 27 colleges and Universities, thus making Chengdu a cultural center at that time. Between 1945 and 1949, with the liberation in Southwest China, many cadres came to Sichuan from all over China. After the founding of the [[People's Republic of China]] in 1949, when three important railways were under construction in Southwest China, a large number of professionals and other technicians were transferred into Chengdu to offer help.

| − | Chengdu is also a city of rebellious and revolutionary tradition. In history, it was the center of a couple of peasant's uprisings and revolutions. In the early Northern Song Dynasty (960-1127), [[Wang Xiaobo]] and [[Li Shun]], the rebel chiefs, started their uprising in [[Qingcheng]] City and soon later established their government in Chengdu. In the late Ming Dynasty (1368-1644), [[Zhang Xianzhong]], rebel chief of the peasants uprising, also chose Chengdu as the capital city for his kingdom. In the Revolution of 1911, people in Chengdu launched an intensive campaign to protect the railways against government nationalization, and was followed by a wave of revolutions throughout Sichuan province. And it also pioneered another greater revolution in October 10, which was known to the Chinese people as the [[Wuchang Uprising]], an important event in modern China. Mr. [[Sun Yat-Sen]], Father of China's democratic revolution, spoke highly of Chengdu people in the revolution. After the [[May 4th Movement]] in [[1919]], Chengdu was among the first to send students to France for further study while working part time. Many revolutionary pioneers, including [[Wang Youmu]], [[Zhao Shiyan]], [[Wu Yuzhang]], and [[Che Yaoxian]], lived and worked in Chengdu. In December 1949, to liberate Chengdu, many soldiers sacrificed their lives to create a new world in this old city.

| − | Chengdu has also been famous for its rich cultural heritages. Within its jurisdiction are [[Qionglai]] city, [[Chongzhou]] city and [[Pengzhou]] city, all of which are listed as Cities of Rich Cultural and Historical Heritage by the government of Sichuan province. In November 2000, Dujiangyan Irrigation System and [[Qingcheng Mountain]] (the Taoist Mountain) were ranked as Cities of the World Cultural Heritage by the United Nations Educational, Scientific and Cultural Organization (UNESCO).

| − | Owing to their wisdom, diligence and creativity, from ancient time to present, Chengdu people have been creating uncountable "Firsts" in the fields of economy, science and technology, and on human culture, which include First in Sichuan, First in China and First in the world. These "Firsts" bring up this historical and cultural city and endow Chengdu permanent enchantment and charming demeanor. Lets start with one of the "Firsts" in the world created by Chengdu people. Dujiangyuan Irrigation System was built around 250 B.C and it has been benefiting Chengdu people for so long a time as 2000 years. It is the first in the world. In the year of 61 B.C, people drilled a deep well to tap natural gas in [[Linqiong]] (a city under Chengdu's jurisdiction) and the gas was used in salt making, cooking and lighting. Chengdu Shu Brocade, also named "Brocade Satin", is the earliest brocade silk in the world. The foot-driven loom invented in Chengdu in the Eastern Han Dynasty ( 202 B.C - 220 B.C) was the most advanced in the world at that time. Up to Han Dynasty (202 B.C-220 B.C), Chengdu became the world's lacquer¨Cmaking center and the birthplace of tea culture. In Tang Dynasty, for the first time, engraving printing was invented and widely used in Chengdu. The "Tuoluoni" Scripture and Incantation of Bian Family, the remnant pages of Diamond Sutra of Guo Family in west Sichuan, the remnant pages of the Fan Family history in Chengdu are the earliest existing presswork in the world. In Northern Song Dynasty ( 960 B.C-1126, B.C), merchants in Chengdu jointly issued the earliest paper money in the world, which was called Jiaozi at that time. The local government set up Office of Jiaozi, which was the earliest administrative and savings bank. Now lets talk about the Firsts in Chinese created by Chengdu people. In 250 B.C, Li Bing used stone dolls to measure the water level of Dujianyuan, which is the earliest water gauge in the world. In 141 B.C, Wen Weng, satrap of Shu Prefecture, for the first time in China, established a school run by the local official named "Wenwong Stone House" in Chengdu. In Western Han Dynasty (202 B.C-8 A.D.), Sima Xiangru, [[Mei Cheng]], [[Jia Yi]], Yang Xiong and [[Wang Bao]] laid the foundations of [[Hanfu]] (ode in Han Dynasty ). Meng Chang, emperor of Latter Shu Kingdom ( 943 A.D. -965 A.D.), wrote the first [[spring festival]] scrolls in China, the content of which it that at the end of an abundant year, we welcome with great passion the remaining days of this year, and at the joyous festival, we shout and jump for the upcoming spring. Before 355 A.D, Chang Qu compiled "Chronicles of Huayuang", the earliest existing chorography in China. "Midst Flowers",the first collection of poems in the history of Chinese literature was compiled by [[Zhao Chongzuo]] during the reign of the Latter Shu Kingdom. In 1082 A.D, the earliest pharmacopoeia of China was composed by a famous doctor [[Tang Shenwei]] in Chengdu.

| + | Climate: Located in the bordering areas of the Sichuan northwest highland and Sichuan basin, Chengdu has its own climatic features. First, the eastern part of the city is different from western part in climatic zone, due to the abrupt change of the height from the east to the west. In Chengdu, generally speaking, the west is cool while the east is warm at the same time. Even in the same mountain, the foot of hill is several degrees higher in temperature than that on the top of the hill. This dramatic change in temperature is favorable for the agricultural development. Second, the winter in Chengdu is short, with a long frost-free period of over 337 days each year. The annual average temperature is around 16.4 degree. Even in the cold January, the average temperature is some 5.degrees. It rarely snows. Compared with other areas of the Changjiang River, it is 2-3 degrees higher. Third, there is not much precipitation in winter and spring while it is affluent in summer and autumn with the total precipitation volume of 1,124 centimeters. And this figure is comparatively stable, the ratio of the year with most rainfall and the year with least precipitation being 2:1. Fourth, the climatic elements of light, water and heat almost occur in the same season, which is a very favorable combination to the growth and propagation of the vegetation. Fifth, the wind speed is low. On the plain and in the mountainous areas, the normal speed of wind is around 1 to 1.5 meters per minute. The total sunshine hours average 1,042 to 1412 each year. |
