Li Jun left Songjiang when he arrived in Suzhou on his way back to the court after the heroes of Liangshan pacified Fangla.
At that time, Li Jun pretended to be ill and asked to leave Tong Wei and Tong Meng to take care of him, so that Song Jiang could return to the court first. Song Jiang was afraid of delaying his trip, so he had no choice but to agree. Later, Li Jun met with Tong Wei and Tong Meng, went to Yuliuzhuang to build a ship, sailed from Taicang Port, and finally established a foundation in Siam and became the leader of the country.
