Pang Tong liked to play tricks, and he knew people's hearts better than Zhuge Liang. Although Liu Bei got Jingzhou, he was surrounded by Cao Cao and Sun Quan, and they both hoped to eat Liu Bei's territory, and Liu Bei's identity was very embarrassing at this time. In order to avoid being eaten, Liu Bei set his sights on Sichuan, but Liu Zhang and his son had been operating in the Shu state for many years. Moreover, Shu Dao is easy to defend and difficult to attack, so it is difficult to obtain. At this time, the appearance of Pang Tong clearly analyzed and showed the situation of the Shu state and Liu Bei. He used the upper, middle and lower strategies to help Liu Bei plan the direction smoothly. This is very rare. Liu Bei is a hero. Although he was also aware of The Wisdom of Mr. Wolong in his early days, it was not until pang Tong appeared that he really realized the importance of strategy. As a result, Pang Tong followed Liu Bei, was soon promoted to military division, and handed over half of his troops to Pang Tong, which can be predicted by Pang Tong's wisdom and Liu Bei's respect and courtesy to him. The real reason liu bei was interested in Pang Tong was whether to occupy Yizhou. At that time, Liu Bei hesitated. Pang Tong analyzed Liu Bei's basic situation in Jingzhou and Yizhou, compared public support, strengthened Liu Bei's determination to attack Yizhou, and proposed three strategies. Liu Bei eventually occupied Yizhou, and Pang Tong's credit was indispensable. Pontong has little record of support, or he did not fully demonstrate the talents of a generation of military experts.
