Wei Qi, a native of Yuan Dynasty, was named Zhong Yangzi and lived in seclusion in Penglai Mountain, Pengxi County. He was good at Taoism when he was young, and he was able to discern mysteries. He once served as a military and civilian commander in Qijiang, Nanping and other places. In the early Yuan Dynasty, Wei Qi annotated Liu Ansheng's "Wenchang Dadong Immortal Sutra" in Penglai Mountain, Pengxi County, Eastern Sichuan. In the third year of the Yuan Dynasty (1310), Wei Qi dedicated his "Wenchang Dadong Immortal Sutra Commentary" to Yuan Wuzong, and was rewarded and became famous. His book has been widely circulated throughout the country and has become the main text of Dongjing music in Yunnan, Sichuan and other provinces. Wei Qi made great contributions to the emergence and spread of Dongjing music. Yang Zuoji, governor of Henan Province in the Ming Dynasty and a native of Pengxi, said in "Record of the Construction of Shiyushan Academy": "Yangzi in Penglai Mountain once annotated the "Dadong Immortal Sutra"." This is the earliest record of Wei Qi's annotation of "Dadong Immortal Sutra" in Penglai Mountain, Pengxi County. The documents of "Classic" are included in the Qing Jiaqing edition of "Sichuan Tongzhi".

Dongjing music is a living fossil of music and has been recognized by UNESCO as a precious intangible cultural heritage of all mankind.

"Huaping County Cultural and Historical Materials·Second Series" says: Dongjing music was introduced to Dali from Sichuan in the seventh year of Yongle in the Ming Dynasty (1409). "Nanjian County Literary and Historical Materials Volume 1" also says: It was introduced to Dali from Sichuan in the seventh year of Yongle in the Ming Dynasty, and then spread from Dali to various parts of Yunnan. "Tonghai County Data" also said that it was introduced from Sichuan. "The Music of the Dali Cave Sutra: Preface" states: In the 13th year of the Jiajing reign of the Ming Dynasty (1534), Dali and Xiaguan sent people to Sichuan to practice the Dadong Immortal Sutra and brought back two copies of the Immortal Sutra each. Although there are differences in time among the four theories, they are all clear and must have been introduced from Zitong. These statements are relatively reliable. For reference, Yunnan Tongzhi compiled by Li Yuanyang of the Ming Dynasty can be used as a reference. This book records the situation of Wenchang Palace in various states and counties in Yunnan in the early Ming Dynasty.
