"Orchid Grass".

It was written by Hu Shi, composed by Chen Xiande and Zhang Bi, and sung by Zhuo Yiting. It was included in the album "Campus Youth Music 2" and was released on September 7, 1997. "Orchid Grass" is a classic nursery rhyme that is remembered by many children. The brisk tune is also loved by many people. In my country, this song is also used as the ringtone of the sprinkler truck to remind people that the sprinkler truck is working.

Sprinkler trucks are also called spray trucks, multi-function sprinkler trucks, landscaping sprinkler trucks, water tank trucks, and water trucks.
