There's Someone Under the Bridge

Fifteen years later, Li Yan returned to his hometown in Northeast China, but his father drowned mysteriously under the Hanhe Bridge. It is said that it was so cold that night that the river froze into iron, and no one could explain how he fell into the water. Some people say that it was the "eye of the river" at the bottom of the river that opened its mouth; Some people say that there is a figure standing in the fog under the ice, beckoning him down. On the first night after returning home, Li Yan saw a cloud of fog rising from the center of the ice on the bridge—— When the fog cleared, there was a faint clicking sound from under the ice, like someone tapping the ice with their fingernails and whispering his name. The black wooden box, the string of copper coins, the missing old man, the lights sealed under the ice... He stepped into Hanhe's secret step by step, only to find that the man under the bridge had been waiting for him fifteen years ago. There is not water under the bridge, there is a door under the bridge——
