"Orchid Grass".

Most of the work music for Xi'an's sprinkler trucks is "Only Mom is Good in the World" and "Orchid Grass". In 2015, the song "Orchid Grass" was played.

The sprinkler truck uses the power of the vehicle's engine to drive the vehicle-mounted sprinkler pump through the power take-off. It adds water to the vehicle from the water inlet or transports the water in the tank to each sprinkler head through pipes, thereby realizing various functions. .
