Yu Baosi is nicknamed "God of the Dangerous Road" because of his huge girth and awesome height of about 10 feet, or more than 3 meters.
Mad over the humiliation, Chao Gai, the chief of Liangshan, personally leads a military attack on the fortress.
Song Jiang's determination is further strengthened after Yu Baosi seized more than 200 horses his men have purchased and were driving back to Liangshan, and took them to present to the Zengs.
Song Jiang sets the conditions that Yu Baosi as well as the "Jade Lion" and the other horses of Liangshan be handed over.
Yu returns to lie to the Zengs that Song Jiang is in panic as government troops are arriving to lend them assistance.
Yu Baosi is appointed as the chief flag bearer of Liangshan because of his striking height after the 108 Stars of Destiny came together in what is called the Grand Assembly.
