Playing the piano to a cow is a Chinese idiom, which originated from "Theory and Doubts" written by Mou Rong in the Han Dynasty. This idiom means being reasonable to people who are unreasonable and being elegant to people who do not understand beauty. It is also used to ridicule people who do not look at the object when speaking.

Of course, there is another story. Legend has it that during the Warring States Period, there was a musician named Gong Mingyi. One day, he came to the suburbs. The spring breeze was blowing slowly, the weeping willows were moving gently, and a cattle was grazing on the grass with its head lowered. Gong Mingyi was in a moment of interest. He put on the piano, plucked the strings, and played the most elegant music "The Exercise of the Clear Corner" for the cow. The old scalper remained indifferent and continued to eat grass with his head lowered.

Gongmingyi also used guqin to imitate the buzzing cry of mosquitoes and the whine of stray calves. The old cow immediately stopped eating grass, raised his head, pricked up his ears, shook his tail, took small steps back and forth, and listened carefully. This story shows that it is not that cows don't understand music, but that the songs they play must match the cow's ears.

Benniu Ranch has hundreds of acres of grassland and is known as the Guangdong grassland. More than 20 cattle are raised in the park. The keepers in the park were very creative and wanted to find out whether the cows could understand music, so they specially purchased 2 guitars and played a few songs for the cows while herding the cows.

He was surprised to find that at the beginning, the cow completely ignored his guitar sound and just ate his own grass. After playing for a few days, the cow began to pay attention to the sound of his guitar. As long as he played next to the cow, the cow would stop eating grass and then look up to give him a meaningful look.

He was worried that the cow's memory storage function would be limited if there were more curved bullets, so he played a few songs a day. The cow was slowly deeply attracted by the sound of his guitar. As soon as he played, the cow seemed to have received a notice to attend a concert. It immediately stopped eating grass, walked to him with square steps, and listened carefully, looking like he was a friend of the mountains and rivers.

During the Spring Festival holiday, the ranch turned this project into a tourist experience project, allowing tourists to cast pearls before swine. Tourists who are familiar with this idiom are very happy when they hear it, and everyone wants to verify whether the cow can understand music. Holding the guitar, he started to play at the cow. Although some tourists who didn't know how to play guitar played it indiscriminately, the cow also expressed understanding and listened to it in friendship for a while. There are a few cows who understand music and have a certain artistic temperament who seem to know that tourists play the wrong way, so they responded with their mouths wide open and went to eat grass.

According to the breeder, listening to music is beneficial to the cattle. Playing music to the cows will increase the milk yield. If you listen to music to the scalpers, they will "hear the music and start to eat", and their appetite will increase greatly. Playing music for cows can promote cow labor, and playing music for bulls can calm down the fighting bull, so playing the piano to a cow is actually helpful to the cow.
