General Baipao introduced: In front of and behind the "Shade Marquis", there is a tall white pine in the north and south. They were also planted in the Jin Dynasty. The green crown is more than 30 meters high and the circumference of the white trunk is 5.1 meters, just like two people. The mighty generals guarded the front and back of Chengguang Hall, so Emperor Qianlong named them "white-robed generals" and wrote a poem "Gu Xing Xing": "Five needles are pine and three are qiao. Although the names are slightly different, they are all the same." . There are several trees standing in the ridge, and I don’t know who planted them.”
