Qian Yanqiu () is a Chinese film director, screenwriter, and actor.
He is a graduate of Beijing Film Academy and is most known as the creator and director of the Amazing Detective Di Renjie series.
In 2003, Qian created the Amazing Detective Di Renjie series, starring Liang Guanhua and fellow Beijing Film Academy graduate Zhang Zijian. The series would later have three sequels. Qian also created the Yan Shuangying series in 2009, starring Zhang as the protagonist and Liang as recurring antagonists.
During filming of Mad Detective Di Renjie (ç¥ÂæÂÂçÂÂä»Âæ°), QianâÂÂs script was not used, leading to a dispute on who owned the copyright. Producer Zhang Wenling stated that when the investors hired Qian as director and screenwriter, they signed an agreement stipulating that he only had the right to be credited, not the copyright to the script. However, Qian stated that he had already registered the copyrights of all three of his Detective Di Renjie scripts. This ultimately led to the production company creating a separate fourth entry (ç¥Âæ¢çÂÂä»Âæ°ä¹Âæ è±éÂÂ人æ¡Â), directed by Tan Youye and produced by Zhang Wenling, with many cast members being replaced.
