Heihu Spring is one of the 72 most famous springs in Jinan City, Shandong Province, located on the south bank along the moat of Heihu Spring Street. The wind emits a terrifying roar as it rises through the cave. For this reason, it is known as "hei hu", or "black tiger". The spring water rises from the cave and cascades from stone animal heads from 28 meters high and into a stone pool 13 meters long and 9 meters wide.
