Fujian Tulou is a special type of Chinese building. People built most of them between the 12th and the 20th century. The oldest one has a history of more than 1,000 years.
Tulou is usually a large rectangular（长方形的）or round building with high walls. The walls are made of earth, stones, bamboo and wood, so they are thick and strong. They can not only keep the building safe from the wind and earthquake, but also make it warm in winter and cool in summer. There is usually only one main gate in each Tulou and up to （至多）80 families can live in it. It is like a small city.
UNESCO(联合国教科文组织)chose a total of 46 Fujian Tulou as a World Heritage Site（世界文化遗产）in 2008. Fujian Tulou set a good example for the world. Man can live in harmony（和谐，融洽）with the environment.
