The main hall of Ancestral Hall of Zhou Gongfu faces north and is well structured and magnificent. There are fine wood carvings in brackets, tie beams, column caps and hanging baskets. There are simple and unsophisticated lotus-covered bluestone foundations under bulky stakes. In front of the main entrance, there is an ancient and elegant yacca which is more than 230 years old. It is still flourishing with numerous branches and leaves and is considered as a sign of auspiciousness. People in Lili tell fantastic stories about it.
