Panlong River originates from the mountains in the northern suburbs of Kunming City, and then runs through Kunming City from north to south. In ancient times, the river was tortuous and shaped like a giant dragon passing through the city, hence the name "Panlong". Panlong River is the axis of Kunming's water city style. Its tributaries are as dense as spider webs, making Kunming City located on the plateau better than the south of the Yangtze River. Boating on the river, sitting by the window, lights flash on both sides of the river, and high-rise buildings stand in rows. The slowly flowing river reflects the dim lights, which is moving, prosperous and quiet. At the end of 2019, with the strong support of the municipal party committee and government, Kunming Diantou Company launched the trial operation of the Panlong River resumption of navigation test section, leading Residents to regain Kunming's "water city memory", which has received high attention and wide acclaim from Residents. Residents and tourists can fully experience the hardships and difficulties of Dianchi Lake governance while taking a boat tour of Panlong River. At the same time, they can share the results of Dianchi Lake governance, inspire the enthusiasm of the general Residents to participate in the protection and governance of Dianchi Lake, and always adhere to the concept of "not letting a drop of sewage enter Panlong River" to protect our mother river like protecting our eyes. And actively participate in the action of "loving Panlong River and protecting mother river". It will also become a new highlight and new name card for Kunming's active night economy.
