Black Dragon Lake Park is an ancient scenic spot located in the northern suburbs of Kunming. The Black Dragon Lake Park is composed of two scenic spots: the ancient architectural complex and the "Longquan Plum Exploration". The Qing Shuoqing inscription "Two plum trees and a pool of water, four times of smoke and rain and half a mountain cloud" is a reflection of the landscape features of the park. Legend has it that there is a black dragon diving in the pool, so it is called Black Dragon Pool. Dragon pool is divided into two pools before and after, separated by a bridge, a spring of clear water, a spring of muddy, like the Taoist said that the yin and Yang half of the "Tai Level Figure". The two springs are connected, but the fish of the two springs do not cross the pool, forming a strange landscape of "two waters intersecting, fish do not travel". The ancient building group is built around the pond, and the lower view is the Black Dragon Palace, which was built in the 27th year of the Ming Dynasty Hongwu (1394) and is dedicated to the statues of the Dragon King and the Water Tribe, which is said to be the god of raising clouds and sending rain. Hidden deep in the greenery and built on the mountain is the upper view, namely the "Han Black Water Shrine". In the viewpoint, there are Tang plum, Song cypress, Ming tea, Yuan cedar, Qing magnolia, etc., which were planted by Guo Moruo as "three different trees", and plum blossoms in the Ming and Qing dynasties were all converged here, so ancient plums are gathered here today, as Ruan Yuan said: "Thousands of years old plum blossoms, a thousand feet of pond, the spring breeze first to the colorful Yunnan." The plum garden adjacent to the ancient building - "Longquan Tanmei" is one of the 16 new scenic spots in Kunming, and is the largest plum appreciation resort and research base for plum blossoms in the southwest. Thousands of plum trees, stakes and hundred-year-old plums are gathered in the garden; pavilions, platforms, buildings and pavilions with rich Yunnan local architectural characteristics are scattered among them, overflowing with the silent beauty and quiet contemplative interest of Chinese plum culture. The garden preserves famous monuments of the past generations, such as the convex monument, the Tang plum monument, the Song cypress monument, as well as the tomb and ancestral hall site of Xue Erwang, the Ming loyalty duke.
