What's the toot-toot song in summer?

The song is called "Mouth DuDu". This song is another magical song popular in Tik Tok after Gucci Prada. The most important thing is that Sister DuDu, who sings this song, is also very popular, and countless online celebrities on Tik Tok have co-produced videos with her. Lyrics: The spring breeze blew away a butterfly on the flower branch. I will send you to Beiye, south of the Yangtze River. You said to sit with me and make tea when you came back from sketching the snow season.
