Born in the Jianning period of Emperor Ling of Han Dynasty (168- 172). Xu Shu, formerly known as Xu Fu, liked fencing in Ren Xia when he was young, and later studied there. Because of the war in the Central Plains, he lived in Jingzhou and made friends with Zhuge Liang, Si Mahui and Pang Tong. After Xu Shu played for Liu Bei, he also recommended Zhuge Liang. In the battle of Nagsaka, Xu Shu's mother was captured by Cao Jun, so Xu Shu defected to Cao Cao in the north and became the commander-in-chief from Wei Guan to You Wei. Xu Shu loved fencing when he was young, and then he studied fencing and traveled around the world. When Liu Bei was in Xinye, Xu Shu made a list of blessings, went to Liu Bei and was worshipped as a military adviser. Xu Shu persuaded Liu Bei to defeat Cao Jiang, Lv Kuang and Lv Xiang, fight Coss and take Fancheng. Soon Cheng Yu, Cao Cao's counselor, broke the identity of Xu Shu, saying that Xu Shu's talent was ten times his own. Cao Cao wanted to win over Xu Shu, so Cheng Yu took Xu Shu's mother and used fake books to earn Xu Shu's surrender. Xu Shu recommended Zhuge to Liu Bei before he left, and vowed to "never plan" in Cao Ying. Later, Xu Shu followed Cao Cao to attend Battle of Red Cliffs. At Pang Tong's suggestion, he volunteered to go to Shanhaiguan pass to defend Marten and Han Sui and avoid the Red Cliff fire.

Pang Tong (179-214), a native of Xiangyang (now Xiangfan, Hubei), was a famous counselor and general under Liu Bei during the Three Kingdoms period.

Pang Tong was dull and ignorant when he was young. But his uncle Pang Degong, a great celebrity, spoke highly of him and thought he was unusual. At that time, Si Mahui was a native of Yingchuan, with elegant manners and integrity, and was known as a knowledgeable person. Pang Tong went to visit him. When they met, Si Mahui was picking mulberry trees, so Pang Tong sat under the tree and talked to him. The more they talked, the more speculative they became, so they chatted under a tree until late at night. Si Mahui felt that Pang Tong was really extraordinary, and sincerely praised Pang Tong as the leading talent in Zhou Nan, and praised: "Pang Degong really knows people, and Pang Tong is really different!" Since then, Pang Tong's reputation has gradually become prominent. Pang Degong tied him with Zhuge Liang and Si Mahui, saying that Kongming was Wolong, Pang Tong was Feng Chu and Si Mahui was a water mirror. Pang Tong's "Feng Chu", a counselor with the same fame as Zhuge Liang, avoided the Jiangdong Rebellion in Battle of Red Cliffs and was recommended to Zhou Yu by Lu Su. Zhou Yu joined Cao Ying in offering a "series of tricks", which led to the success of Zhou Yu's fire attack. After Zhou Yu's death, Zhuge Liang took advantage of his funeral to win over Pang Tong, and Lu Su also recommended Pang Tong to Sun Quan, but Pang Tong was not valued because of his ugly appearance and arrogant attitude. So Pang Tong went to Jingzhou to take refuge in Liu Bei. At first it was a county magistrate, ignoring political affairs. Before Liu Bei discovered Pang Tong's talent, he sent Zhang Fei to punish him. So he worshipped Pang Tong as the deputy military commander, praised the strategy with Zhuge Liang, and tutored the sergeant. Later, Pang Tong followed Liu Bei to take Shu, aiming at slaying Yang Huai and Fu Shui Guan. However, when attacking Luocheng, he suspected that Zhuge Liang wanted to take credit, refused to listen to his letter, and rushed to Luofengpo, where he was ambushed by Zhang Ren and shot to death by random arrows.
