A tulou or “earthen building”, is a traditional communal residence found in Fujian Province South China, usually of a circular configuration surrounding a central shrine. Some were constructed out of cut granite or had substantial walls of fired brick

The Fujian Tulou is probably the last one, built in 2008 and it looks like this:

The Fujian Tulou is including Chuxi tulou group, Tianluokeng tulou cluster, Hekeng tulou cluster, Gaobei tulou cluster, Dadi tulou cluster, Hongkeng tulou cluster, Yangxian lou, Huiyuan lou, Zhengfu lou and Hegui lou, and it is considered  as “exceptional examples of a building tradition and function exemplifying a particular type of communal living and defensive organization in a harmonious relationship with their environment”.

I really like the concept of these buildings, and I heard that it were also made to deposit things, which means they are very spacious. The relationship between people living in that area should be very strong.
