Cao's academy is the only garden-style Academy in China. It is said that every person in the Academy will plant a sweet-scented osmanthus tree in the osmanthus porch. Every time osmanthus blossoms in the season, the fragrance is overflowing. Outside the academy is the Peach Blossom Dam. On the other side of the river is a nunnery. It is said that Cao Zhenyong's sister built and lived there all her life in order to fulfill her promise.
