What traditional cultures do the characteristics of Hakka folk houses reflect in China?

Hakka folk house is a wonderful flower of ancient Chinese architecture, which is independent of the world folk house architecture art forest with its long history, unique style, huge scale and exquisite structure. The caste social characteristics and architectural characteristics of Tulou folk houses are closely related to the history of Hakka people. Wherever Hakkas go, their surnames always live together. Besides, most Hakkas live in remote mountainous areas or dense mountainous areas. At that time, not only building materials were scarce, wolves, tigers and leopards were noisy, but also they were afraid of local people's harassment, so Hakka people created "defensive" castle-style building houses. In this way, the unique architectural form of Hakka dwellings-tulou was formed.

From the research of history and architecture, the architectural style of tulou is a self-defense living style for national security. At that time, under the situation of Japanese invasion and civil war every year, Hakkas who moved their families traveled thousands of miles to other places and chose an architectural way conducive to family reunion and defense against war. Descendants of the same ancestor form an independent society in a tulou, with honor and disgrace. Therefore, restraint from the outside and cohesion from the inside are probably the most appropriate induction of tulou.
