Um, I remember it was a movie called Little Lark, which is also a very classic and old movie. This movie starred Gu Mei in the lead role and even had a bunch of popular singers in cameo appearances. This is a comedy about the love affair between a singer and a reporter. Gu Mei plays the famous singer Little Lark, who comes to Hong Kong from Bangkok to sing, and coincidentally encounters the impudent reporter Lau Sze-tai played by Chan Hau; Sze-tai, in order to find out the inside information of the Peach Sex Incident, pretends to be the entertainment magnate of the South China entertainment industry to get close to Little Lark, which is a lot of laughs, but also leads to a real relationship. The movie features a number of classic songs, including Gu Mei's "Empty Dreams", Fong Yat Wah's "Flower and Moon" and Poon Siew Kiong's "Lover's Tears".
