It was built in the Zhengtong period of the Ming Dynasty and expanded in the 27th year of Qianlong (1762). , more than 600 years ago. It integrates Chinese national architectural art and Hakka cultural connotation, and is a relatively complete preserved typical Ming Dynasty building. The door of Yanqing Hall does not face the lobby, but opens to the southeast of the house. You must pass through an inner door to see the stage, middle hall and upper hall. The structure of this kind of gate is similar to that of a courtyard house in Beijing. The hall can accommodate hundreds of people to worship ancestors and have meals. There were originally more than 40 merit plaques with carved dragons and colorful borders, as well as degree gold medals. Now only the plaque "The Dragon Teng and the Phoenix Rise" erected in the 12th year of Yongzheng (1734) remains. In addition, there are also a gold plaque (remnant) of the Jinshi carved in the Guangxu period, a shrine, a genealogy case, a photo box, a stone incense burner, etc., which silently tell the glory of that year.
