The central idea of ??Boya Guqin: This article tells a story that has been passed down through the ages of meeting a close friend in the mountains and flowing water.

The sincere friendship between the protagonists Yu Boya and Zhong Ziqi is touching. It expresses the sincere friendship between friends who understand and appreciate each other, as well as the emotion of cherishing a friend who is hard to find.

"Bo Ya Gu Qin" is a story that happened when Boya was on his way to visit his relatives. This story was first handed down orally among the people, and there is no precise record in history. Among the ancient books, "Lu's Spring and Autumn Annals" contains folk stories about Boya Juexian, which established the noble standards of interpersonal relationships and friendship of the Chinese nation.

Translation of "Bo Ya Drum and Qin":

Bo Ya was playing the harp, and his friend Zhong Ziqi was enjoying the music. When Boya played the piano, he thought about climbing Mount Tai. Zhong Ziqi said happily: "You play so well! I seem to see a towering Mount Tai!" After a while, Boya thought about Liu Shui again, and Zhong Ziqi said again: "You play so well! I seem to be watching "Arrived in the vast ocean!"

Zhong Ziqi fell ill and died. Boya was very sad. He broke the qin and broke the strings. He never played the qin again, thinking that there was no life left in the world. There was no one worth playing for. This is true not only for piano players, but also for talented people. Although there are talented and virtuous people, there is no one to communicate with them. How can a sage show his loyalty? A good horse does not become a thousand-mile horse by itself, but waits for Boya and then turns into a thousand-mile horse.
