Introduction to the main courtyard: The second courtyard is the main courtyard, where Ma Bufang and his family lived and worked. It was also the political and military center of Qinghai Province. The word "Xinlu" in the main courtyard was inscribed by Lin Sen, the chairman of the National Government at that time. In front of the door, there is a Taishi chair carved from the roots of a century-old tree. Visitors can sit on it.
