Famous Neo-Confucianists are located in the middle section of Liukeng Middle Alley, sitting on the north alley. It is the former residence of Dong Sui, a doctor in the Ming Dynasty and a member of the Ministry of Punishment. There is a large porch in front of this house, for one entry and three bays. In front of the main entrance, there are a pair of round carved red stone lions. Although they have been mottled and ancient after hundreds of years of vicissitudes, their majesty still exists. On the lintel hangs a large plaque of "Master of Science", which was written by Shaobao, the prince of Ming Dynasty, and Zeng Tongheng, the minister of officials. 6 meters in front of the porch, there are plaques and couplets engraved on the shadow wall-style brick workshop of the Ming Dynasty, which were written by Luo Hongxian, the champion of Jishui.
