Why is Tan Xinpei called "the king of the music world"?

Tan Xinpei has opened up a new world for the performing arts of the old Peking Opera students, with far-reaching influence, and played a connecting role in the history of Peking Opera. For more than half a century, many old Peking Opera students have favored boys over girls, and they are called "Tan School". Tan Xinpei used his whole life's painstaking efforts and energy to inherit and develop the traditional opera art in China. Since then, this old-fashioned art has been further standardized and systematized, which basically stabilized the pattern of Peking Opera. During his 60-year drama career, he has occupied various styles of stage in China and won audiences at all levels, from the palace to the villages and towns. The Tan School art he created represents the traditional style of China opera in many aspects. He inherited the essence of the Huizhou School and the Han School. He is both civil and military and invincible in troubled times. He developed in an all-round way by singing, reciting, doing and playing, which initiated the "charm school" and gradually brought Beijing opera into a beautiful realm. Tan School, founded by him, is the most widely spread and influential art school with the most flourishing branches and leaves. In the history of Beijing opera, it has always been recognized as the mainstream school among the old performers. Later, important old schools such as Ma, Yan and Yan were all derived from Tan School.
