Introduction to the courtyard: Pines, cypresses, bamboos, and willows are all in various shapes, and all kinds of flowers are blooming and fragrant in all seasons. There are two symbiotic trees in the west of the courtyard, one is a cypress tree and the other is a banyan tree. Hundreds of years of ups and downs have become so tightly intertwined that some people jokingly call them "General Wan embraces Miss Bai."
