Introduction to the four courtyards of the main house: The four courtyards of the main house start with a hanging flower gate tower. The green carving on the top is a rope diagram of three lions dancing, which is homophonic to mean five generations living under one roof. The ropes are endlessly entangled, which represents wealth and wealth. The lion dance and hydrangea show is to come. The following four large seal characters "Duan Jie Yi Yi" teach future generations to be honest, modest and courteous in doing things. This is also the family motto of the Kang family.
