1, the largest artificial lake in Peking University, is located in the north-central part of the campus. The shape is u-shaped. There is a stone fish sculpture in Hunan, and there is an island in the middle of the lake, which is connected with the north bank by a bridge. There is a stone boat at the southern end of the central island of the lake. There are Bell Tower, Linhuxuan, Flower Bed and edgar snow on the lakeside, and Boya Tower on the east coast. It is one of the landmark landscapes of Peking University.

2. The unnamed lake was named by Qian Mu, a professor from yenching university, when he was teaching in yenching university in 1930s.

People enter from the west gate of Peking University guarded by stone lions, and not far away, they can see a pair of beautiful China watches standing on the half-empty ground surrounded by the office building and Xiantang. Continue to stroll eastward, no matter which way you enter the garden space with the unnamed lake as the main body, you will feel suddenly enlightened. In the whole Yan Garden, the unnamed lake is more like a vast ocean. Under the action of light, the lake seems to have thousands of stars moored, emitting ever-changing light. On the unnamed lake, the tower shadow of the lake can be seen in the east; West can watch the sunset in the bell tower; In the south, there are mountains and lakes; The architectural shadows in the north are full of poetry and painting. Therefore, some people sum up the essence of Yan Garden as "one tower and lake map" (that is, the integration of education and teaching, Boya Tower, Weiming Lake and Peking University Library).
