Introduction to Dongtian Yibi: The building is a small house. Because there are empty windows on three sides, it can also be called a pavilion. Therefore, the place is located in a small stone forest courtyard, like a piece of jasper in the blessed land of cave heaven, hence the name. This building existed during the Liu family's time, and was called "Dongtian Yibi" during the Sheng family's time. After liberation, it was called "Stone Forest House", but now its original name has been restored.
