"The name Taizi literally means "crowned prince". During the late Warring States period, Jing Ke, an assassin sent by Crown Prince Dan of Yan for a mission of killing King Zheng of Qin, failed in the attempt. The Qin state retaliated with a massive invasion to conquer the Yan state. After the Yan state fell, Crown Prince Dan fled far into the Liaodong region, and was eventually tracked down and slain by the pursuing Qin forces. According to the legend, the prince's last site of refuge was at the bank of this river, hence the name."
