There is a Qingshui River in the west of Changbai Mountain and at the junction of Fusong and Dunhua in the upper reaches of Songhua River. There is a magical water near Qingshui River, which is called "potion" or "medicine spring" by local people. Legend has it that during the late Qing Dynasty and the Republic of China, ordinary people had difficulties in life and had no money to treat diseases, so they went to the medicine spring to get water to drink. After drinking this water, they may have minor injuries, not minor injuries. As a result, the news spread from one village to another, and all the people in Shiliba Village went to fetch water.

During the puppet regime, Japanese soldiers heard about the magic of the medicine spring, so they sent people to take care of it. From then on, ordinary people can't drink the water from the medicine spring to cure diseases. After Japan's defeat and retreat, it tried to blow up the medicine spring, but the water in the medicine spring helped like heaven. Although it was bombed, the spring water was still flowing.

After the founding of New China, especially after the reform and opening up, people want to develop and utilize medicine springs. A cadre in Lushuihe Town, Fusong County personally brought a bucket of medicinal spring water to the relevant departments of the provincial capital for testing, which confirmed that the medicinal spring water is a kind of high-quality mineral water and contains many elements beneficial to human health. From this point of view, it is reasonable for local people to use this water to treat diseases.

However, why can medicine spring cure diseases? Did the water quality of Yaoquan change after and before the Japanese bombing? It is still a mystery.
