秦琼
Zuo Tiancheng (左天成) was a fictional general guarding the Sishui Pass. He was hardly mentioned in the book Shuo Tang, but he was very popular in folk cultures. He used a golden blade as his weapon and he was regarded as a top warrior in Sui Dynasty. He became famous in a young age, when he bravely ambushed a strong troop from a major Turks tribe in northern frontier. He used to fight alone against the Wangang Five Tigers (five best warriors in Wagang Fort, i.e. Qin Shubao 秦叔宝, Qiu Rui 邱瑞, Cheng Yaojin 程咬金, Wang Bodang 王伯当 and Shan Xiongxin 单雄信). The first time he lost in a battle was when he was defeated by Pei Yuanqing. He was always loyal to Sui Dynasty and was eventually killed by Xiong Kuohai during another battle.
