Archway introduction: The beauty of the Chang Family Courtyard is mainly displayed in three aspects. First of all, there is a wooden archway built in the middle of the inner courtyard of every Founder's courtyard, with small and exquisite cornices and brackets. There are brick-carved walls on both sides of the archway, which are as graceful as cable ties inlaid with gems, adding the finishing touch of the beauty of southern gardens to the square and majestic northern courtyard. This archway flower wall divides the main courtyard into five inside and five outside, five inside and four outside, and three inside and five outside. It has a unique style.
