Jinan is not called Quancheng. There are many springs, but there are not many names that can be called. In addition to the number one Baotu Spring, the number of Black Tiger Springs is the most famous. Black Tiger Spring is located on the south bank of the Liberation Pavilion on the edge of the Jinan moat. It is also a famous landscape in Jinan. The people who come here every day to get water have become a landscape. Jinan is one of the few cities in the country with a complete moat. The spring water of this city flows into the moat and finally gathers in Daming Lake in the north of the city. The moat water is very clear, and the weeping willow branches and leaves are floating around the river. Jinan Mohe River officially opened on December 29, 2010. It connects the four major spring groups, including Black Tiger Spring, Baotu Spring, Wulongtan and Pearl Spring, to form a new spring water sightseeing landscape belt. The rockery on the shore is layered, and the spring water drops in turn, splashing a piece of water, giving a crisp sound. Citizens who come to Black Tiger Spring to get water every day have become part of the life of the old Jinan people. There are many springs in Jinan that can take water. Black Tiger Spring is the most famous. The moat is 6.9 kilometers long and can be visited by boat. Along the way, you can enjoy the ancient city style through Baotu Spring Park, Wulongtan and Daming Lake and other well-known scenic spots in Jinan. The maximum surge of Black Tiger Spring is about 41,000 cubic meters per day, second only to Baotu Spring, ranking second in Jinan Zhuquan. The water is ejected from the hole through the dark passage from the head of the stone-carving animal with an elevation of 27.88 meters, resembling a waterfall.
