He Qian Daochang is a Tik Tok blogger on the short video creation platform, and bgm refers to background music. When creating videos, this blogger often uses a piece of music as bgm, and this song is "Agreement under the Cherry Blossom Tree".

The agreement under the cherry blossom tree was sung by Wang Xiaojin and a lie. This song has a cheerful style and catchy lyrics. I have gained a lot of listeners since I went offline.
