It also implied that, he said, there are flaws with the creativity and techniques of movie production and the market.
"It is important that everyone who takes part in the process of movie production tries their best to be on par with world-class standards. That is the only way that China can improve its level of filmmaking," he said.
Jia has also played a key role in launching a film festival in Pingyao, Shanxi province in 2017.
He said he hoped the film festival, which is set to be held for the third time this year, will help introduce more high-standard foreign films to Chinese audiences.
As one of the few lawmakers representing the film industry, Jia has called for greater efforts to support the development of vocational education for the film industry during the legislative sessions this year.
"There are various posts involved in filmmaking, such as cinematographers, sound designers, makeup artists, hairstylists. The level of Chinese filmmaking will surely improve if more vocational institutions dedicated to the art form can be established," he said.
He added that the artistic and technical merit of a film could not be achieved solely by a group of creators.
Rather, it is built from each detail and each procedure of filmmaking. Jia also made an appeal to revise the copyright law to allow directors to become the copyright holders of films.
"It is very common practice that film directors are the copyright holders of films in the West. It is important for directors because it would allow them to enjoy the dividends from the copyrights of films," he said.
Jia said that he is on course to write a screenplay, and there is a chance that another film will be put into production by the end of this year.
