The Jianyi Museum, located between Tianxin Pavilion and Baisha Ancient Wells in Changsha, is a cultural brand built with a huge investment to protect the 140,000 Sun Wu period chronology Jianyi unearthed in Changsha in 1996. Due to the lack of historical materials in the three kingdoms, this batch of Wu Jian is considered to be another "century archaeological discovery" in China after the oracle and Dunhuang documents of Yinxu. It is worth seeing.
