There are two creeks near Chee Shan Rock.  The southern is called Wai Shuang creek; the northern called the murky creek for its murky water.

Legend has it that the murky port used to be a clear and beautiful creek.  However, during the civil war, once after the Drungs lost a battle and hid in Chee Shan Rock, the Chuans tried to lure them down from the hills.  So the Chuans promised that the Drungs could come down if they want to come down to achieve peach,but they must come down in threes with their braids tied to each other.

Later that night, the Kai King told them in dreams that there is a trick involved and that it was a dangerous trap.  But few didn't take notice of the dream and came down the hills.  They were brutally murdered and couldn't escape fast enough because they were all tied up.
