As far as I know, the movie that Li Xian and Chen Linong are working on is called " Moonlit Night on the Spring River." This was a movie that was released in 2021. It was directed by Li Shaohong and starred Li Xian, Chen Linong, Mao Xiaotong, Bai Yu, and other actors. The film was adapted from the Tang Dynasty poet Li Qingzhao's "Dream", which told the story of the Tang Dynasty poet Li Qingzhao and her husband Zhang Tingyu.
