The Zili Village Diaolou Group is located in Tangkou Town, Kaiping City, Guangdong Province and is one of the world cultural heritage sites. Zili Village is composed of three natural villages with the surname Fang: Anheli (commonly known as Litouzui), He'anli (commonly known as Xincun) and Yonganli (commonly known as Huangniling). The first village to be built was Litouzui, which was opened in the 17th year of Daoguang reign of the Qing Dynasty (1837 AD). It was named because the terrain resembled a plowshare; several households in Yong'anli moved from Huang Village of Shengping Village Committee; and in He'anli The village was built in the 31st year of Emperor Guangxu's reign in the Qing Dynasty (1905). There are 15 watchtowers in Zili Village with different styles, exquisite shapes and rich connotations. They are outstanding representatives of Kaiping watchtowers in their heyday. Zili Village watchtowers were mostly built in the 1920s and 1930s. They were built by local overseas Chinese to protect the lives and property of their relatives in their hometown. The Zili Village Diaolou skillfully integrates traditional Chinese rural architectural culture with Western architectural culture. It rarely reflects the extensive exchanges of Chinese and Western culture in rural China in modern times. It has become a monument to the Chinese overseas Chinese culture and a unique architectural art landscape in the world. The building contains complete furniture, living facilities, production tools and daily necessities, which are rich and interesting and bear witness to the culture and life of overseas Chinese at that time.
