Introduction to wood carvings: The wood carvings in the Chang Family Courtyard are mainly wood carvings of windows, door frames, screens, furniture and partitions in the residence. The patterns are ever-changing, the modeling techniques are different, and the wood is diverse, just like wood carvings. The exhibition dazzles visitors. Unfortunately, wood is not easy to preserve and the damage was very serious. The Chang Family Courtyard is a representative example of Confucian merchant architecture. The interior layout is very particular, reflecting the stability, simplicity, proportion and appropriateness of the scholarly family. The indoor chess, calligraphy and painting, the four treasures of the study, exotic flowers, and landscape bonsai are different from other Shanxi merchant houses. As a Confucian businessman's house, it has its own unique features and is refreshing.
