Introduction to the former residence: Zhou Dunyi's former residence was restored and completed in 2011. It has blue brick and blue earth walls on the outside and a pure wooden structure inside. The former residence was built in the early Northern Song Dynasty and is a typical two-story ancient rural building in southern Hunan. Due to its age, only a few stone steps from the original residence remain. The existing building was restored and rebuilt on the original site in 2010 in accordance with the principle of "imitating the past as old as the past and repairing the old as the old". It covers an area of 300 square meters.
