The architectural style of Chaoyang Tower is a fusion of architectural styles of the Yuan and Ming dynasties. It is a landmark of Jianshui Ancient City, an important landmark for water tourism, and a symbol of the preservation of the important towns of southern Anhui in the past six centuries. There is a couple of praises: "Dongyu Boyun, male is eight hundred miles away from southern Xinjiang; the strong Zhuangshan River is called the first floor of the government." Chaoyang Building has been listed by the State Council as a national key cultural relics protection unit. The large number of historical photos displayed in the Chaoyang Building opened up another door to my impression of Yunnan. This door is different from the beautiful imagination of the south of the clouds. Let me be clear about the difference in history of Yunnan Province as a border province in the southernmost province of China.
