The interior design of Haisan Bureau is actually quite similar to a middle-size residential house. The main gateway of the house is on the east, surrounded by walls with two arches above. The arches are respectively decorated with a sword lion and Chinese characters. There is no difference in its baiting and main hall from the ones in common people's houses. The wooden sculptures and window frames are beautiful in blue tones. The mountain-shaped walls with delicate adornment in the main hall are one of the very characteristics of the whole structure. The eight subjects of exhibition inside Haisan Bureau are biographic notes and data, art and folk skills, scenic spots and historical sites, life, shrines, Wangye and its religious belief, the apotropaic things for residential houses, and the future of Anping.
