Singing instrument is a peculiar wine container. When it is empty, it leans to one side. When it filled more than half of the jar, it stood up firmly. When it is full, it turns upside down. The enlightenment of this singing method is that we can't be complacent, and complacency is a somersault.
Qi Huangong, one of the five tyrants in the Spring and Autumn Period, liked this instrument very much before his death. There is always a singing instrument on the right side of his seat, warning himself not to be complacent. After Qi Huangong's death, when the people of China built this vessel for him, they did not forget to put it in a temple to worship their ancestors.
Once, Confucius led his disciples to visit Qi Huangong Temple. When he saw this vessel, he didn't know what it was, but the person who looked after the incense in the temple knew it was a singing instrument. Knowing the origin of singing instruments, Confucius told his disciples the story that Qi Huangong put singing instruments on the right side of his seat to warn him, and so did educating his disciples to read and study. Complacency is bound to suffer. When Confucius returned, he also asked someone to make one and put it on the right to warn himself. In the Northern and Southern Dynasties, the famous scientist Zu Chongzhi also made a Song Qin for Xiao, the son of Emperor Wu of Qi, which was very successful.
Perhaps this singing instrument was lost later, or later generations thought that words could express their thoughts more accurately, so they used inscriptions instead of singing instruments and placed them on the right. This has become a veritable motto to warn and spur yourself.
