Introduction to Rixin Building: Rixin Building was built in the 31st year of Wanli (1603). It is a square building that absorbs the characteristics of the courtyard-style architecture in the Central Plains area and integrates the traditional Fulao Tulou culture. Among the "Wanli Three Buildings", the Rixin Building is the highest and largest with a square plane. It is the first courtyard-style earth building in Fujian. Due to the serious damage, its original appearance can no longer be seen clearly, so it is called the "Old Summer Palace among earth buildings".
