Yunnan historical masterpieces

Most of the history of Yunnan is recorded in the history books of the Central Plains Dynasty, and there are chapters reflecting Yunnan in the twenty-four histories. A unique book is Schumann, a historical book of Nanzhao written by Fan Chuo in the Tang Dynasty, also known as Yunnan Annals. It has ten volumes, of which Yunnan is the first, the source of mountains and rivers is the second, the six imperial edicts are the third, and the classification is the fourth and sixth. Fifth, Yunnan ranks sixth in cities and towns, seventh in Yunnan products, eighth in barbarian customs, ninth in barbarian religions and tenth in barbarian frontiers. The traffic roads, the location of mountains and rivers, the distribution of Liu Zhao and other ethnic groups, the setting of administrative districts, the distribution of cities and towns, the status of local products, the customs and habits of various ethnic groups, the social organization structure, the surrounding ethnic groups and the country names are described in turn. Although Nanzhao recorded in this book is now Yunnan, Fan Chuo has never been to Yunnan, and the writing of this book is mainly based on Wei Gao's "Opening Southwest" and Yuan Zi's "Yunnan", especially the latter is important. There are many accounts of Nanzhao history in the Tang Dynasty, except Schumann, which is still spread in the world, and other books have long been lost. Therefore, this book has high historical value and is regarded as the oldest local chronicles in Yunnan.
