What is the background music of cctv5 news weather forecast?

Song: After the completion of "Fishing Boat Singing Late", Pu retired from the music scene. However, this song is loved by Chinese people because it was adopted as background music by CCTV prime-time program Weather Forecast. When Pu adapted and played this piece with Yamaha's three-row keyboard, he didn't expect it to be the golden background music of prime-time programs, and he didn't expect it to affect so many people in China.
