Shanzhai

From Wiki China org cn

The word "shanzhai" originally means "mountain village," but the term was given a new life in China. "Shanzhai" has taken on a broader meaning, denoting fake, unprofessional or homemade, a slang term for anything that steals ideas or styles from already well-known stuff. There are shanzhai products that clearly infringes on intellectual property rights, but other shanzhai things could be the result of parody or following the same trend.
