The emissary of Qi was like a beam, and Sun Bin regarded it as a criminal, saying that it was an envoy of Qi. Make it strange and steal it. Qi will treat Tian Ji well and treat him warmly. Avoid the number and be the son of Qi. Grandson sees that his horses are not far apart, and there are three generations of horses. So the grandson said to Tian Ji, "If your brother shoots again, I can let you win." Tian Ji, with the king and his sons, shot at his daughter. Talking about quality, Sun Tzu said, "Now, you should be better than each other, better than each other, better than each other." Three generations later, Tian Ji won again. He won Wang Qianjin. Therefore, avoid entering Sun Wang. Wang Wei asked the art of war and thought he was a teacher.
When the envoy of Qi came to Daliang, Sun Bin secretly came to see him, regarded him as a criminal, and touched the envoy of Qi with words. The emissary of Qi thought this man was extraordinary and secretly drove him to Qi. Tian Ji, the general of the State of Qi, appreciated Sun Bin and was very polite to him. Tian Ji has raced with the Duke of Qi for many times, and gambled to win. Grandson noticed that all their horses can run equally, and they are divided into upper, middle and lower classes. So Sun Tzu said to Tian Ji, "Just make a big bet and I will let you win." Tian Ji believed it, agreed with him, and won the bet with Qi Wang and his son. When the competition came, Sun Tzu said, "Please use your inferior riding horse against their superior riding horse, please use your superior riding horse against their medium riding horse, and please use your medium riding horse against their inferior riding horse." All the third-class horse races are finished. As a result, Tian Ji won two games in one game and finally got the reward from the king's daughter. So Tian Ji recommended his grandson to Qi Weiwang. Wang Wei asked him about the art of war, so he was appointed as a military adviser.
