The reason why the spring water of Yangtai Mountain in Haidian District does not flow is because the groundwater level is falling with the construction and development of the city, so it does not flow.
Yang Taishan's cloud-flowing spring in Bei 'an River area of Haidian has a long-standing reputation, and Jinshan Temple built by the spring is secluded among them. Yang Tai is a scenic spot with Miaofeng ancient incense road as the main line.
