The background music in the trailer of "Detective Chinatown 3" is "The Past Can Only Be Reminisced".

"The Past Can Only Be Reminisced" is a classic old song, sung by You Ya, lyrics written by Lin Huangkun, and composed by Liu Jiachang. It was a huge success when it first came out in 1970, causing a sensation in the Chinese music scene. Many famous singers have covered this song at different times, such as Teresa Teng, Tsai Chin, Gao Shengmei, and Han Baoyi. In "Detective Chinatown", "The Past Can Only Be Reminisced" appears as an interlude and is covered by the film's leading actors Chen Sicheng and Wang Baoqiang.

Song MV

In the form of a documentary, it presents the highlights of the collaboration between Chen Sicheng and Wang Baoqiang since they met. There are behind-the-scenes footage of this collaboration in "Detective Chinatown", especially those ten years ago. The popular "Soldier Assault" is the main line, and old friends such as Zhang Guoqiang and Zhang Yi appear to help recall their youth. Different scenes show the deep brotherhood between them in different periods, and also express different musical connotations.

This promotional song carries the warm emotions between Chen Sicheng and his brothers along the way, and those young, frivolous and happy times will always be deeply recorded in my mind. I believe that the release of the MV will make the protagonist sigh and the viewers will be moved.
