This kind of music organization existed in ancient China, and can be traced back to the Han Dynasty at the earliest. In the Han Dynasty, because the economy was already very good, it was said that Emperor Wu of the Han Dynasty changed dynasties and ordered the establishment of Yuefu, which was very important at that time. You should know that Emperor Wu of Han Dynasty likes music very much. He ordered the establishment of Yuefu, where people gathered music and folk songs collected from all over the world, then compiled new songs and gave them to professionals to enjoy on the birthdays or festivals of emperors and ministers.
At that time, when Yuefu was at its peak, there were more than 800 people, all musicians, writers and artists from all over the world. When they get together, fresh songs or dances are born every day. When the emperor's ministers are free, they will go to Yuefu to enjoy their music performances.
In fact, Yuefu at that time was like a military band or troupe now. It's just that Yuefu served the emperor's ministers at that time, and now Yuefu serves our broad masses of people. This also shows from another side that the economy of the Han Dynasty was very prosperous at that time, and you could enjoy music and song and dance performances in your spare time.
