What is the historical significance of Kaiping Diaolou?

Kaiping Diaolou rarely reflects the extensive exchange of modern Chinese and western cultures in rural areas of China; It combines the unique architectural art of traditional rural architectural culture in China and western architectural culture, and becomes a memorial monument of overseas Chinese culture in China. This is also the most convincing historical testimony that China immigrant culture and different national cultures influenced each other, merged with each other and promoted the common development of mankind in that historical period. It also highlights the process of overseas Chinese and people in China actively accepting western culture. At the same time, the rich and changeable architectural style of Kaiping Diaolou has condensed the architecture of many countries and regions in different periods in the history of western architecture, and has become a unique architectural art form, which has greatly enriched the content of the history of local architecture in the world and changed the local humanities and natural landscape. In Kaiping City, watchtowers are spread all over urban and rural areas. There are more than a dozen watchtowers in a village, and there are at least 23. From Shuikou to Lily, from Tangkou to Qi Gang and Chishui, it's dozens of kilometers across, which is spectacular. These towers are the witness of Kaiping's political, economic and cultural development. They not only reflect the history of the people in the hometown of overseas Chinese who struggled hard to defend their motherland, but also are a living museum of modern architecture and a unique art gallery. It can be said that as a hometown of overseas Chinese, architecture and art, the characteristics of Kaiping are obvious on the watchtower. Protecting and excavating the bunker resources is of great significance to the study of overseas Chinese history and architectural art, the development of tourism resources and the education of collectivism, patriotism and socialism.
