Introduction to the Du Ancestral Hall: The ancestral hall was first built by Du Shi, the eighth generation ancestor, and mainly worships the ancestors from the first ancestor to the second branch of the three sects. It is a hall for worshiping ancestors, commemorating and spreading the merits of ancestors, and inspiring future generations. The book hanging on the ancestral hall has a couplet that says, "To serve the country and carry on the family is nothing more than to be careful and make a decent man, and to work hard and encourage learning is nothing more than to raise filial sons and grandsons for continuous work."
