Introduction to the Yao Family House: The Yao Family House is located in Sanjia, facing east and west, with three rooms in width and seven entrances from the front and back. It is the residence of officials and officials registered in Kongcheng Old Street. It can be called the rich residence of officials and gentry in Kongcheng. A masterpiece that embodies the feudal ethical concepts and feudal moral order of the landlord class since the Ming and Qing Dynasties: "equal superiority and inferiority, order of elders and younger ones, distinction between inside and outside". The golden osmanthus and silver osmanthus trees in the second courtyard are both over 150 years old. When the osmanthus blooms in August every year, the fragrance is so fragrant that half of Kongcheng Old Street is surrounded by the fragrance of osmanthus. The local people in the old street have a custom. Every year during the high school entrance examination and college entrance examination, parents bring their children to these two trees to make wishes, hoping that they will win a laurel, be named on the gold medal list, and honor their ancestors.
