Old customs and superstitions begin on the thirteenth day of the first lunar month, and then two days in advance every month will be Pepsi taboo day. Legend has it that Song Taizong's Zhao Er snake was tricked by the Liao State into going to the north to negotiate. Yang Jiajiang, led by Yang Jiye, went to protect the Northern Expedition, and marched to the front of Lianglang Mountain. Yang Jiye thinks that the soldiers have committed the taboo of place names this time. His surname is Yang, and when a sheep meets a wolf, it is difficult to win. He warned his children that officers and men should be careful. Dalang died for the King of Song; Jiro was short-lived and dead; Saburo stepped on the paste; Shiro lives in Banbang, and Shiro is afraid of death and becoming a monk.
