Introduction to the ancient Naxi blockhouse: The Naxi ancient blockhouse is located on the Kanzotong Ranch. It has 4 floors and is more than 10 meters high. Judging from the location and architectural style of the ancient blockhouse, it dates back to the second year of Longqing in the Ming Dynasty to Chongzhen. It was built by the ancient Naxi people during the reign of Lijiang Mu clan chieftain in the twelfth year (1568-1639). The entire watchtower is made entirely of stones without any sticky auxiliary materials. Although it has lasted for more than 400 years, except for the corrosion of wooden doors and windows, the main building is still well preserved, which is a miracle.
