Introduction to Zhujin Tower: Located in Zilingzhou in the east of the garden, it is the residence of Jia Yingchun, the second lady of the Jia family, so the poem name of Yingchun is "Lingzhou". The interior windows are lonely, the screens are dim, and the water plants outside the door are green and purple. They are humorous and desolate. They are an image portrayal of the tragic fate of the man nicknamed "Er Wood" who "married by mistake to the Zhongshan Wolf" during the Spring Festival.
