In which dynasty did the story of horse racing in Tian Ji take place?

In the 4th century BC, China was in a state of separatist regime, which was called "the Warring States Period" in history. Sun Bin, an official of Wei State, was persecuted by his colleague Pang Juan, rescued by the envoys of Qi State, and then arrived in the capital of Qi State.

The envoys of Qi introduced him to Tian Ji, the general of Qi, and Tian Ji asked Sun Bin for advice on the art of war. Sun Bin spoke for three days and nights, and Tian Ji was particularly admired. He regarded Sun Bin as a distinguished guest, and Sun Bin was also very grateful to Tian Ji, who often gave him advice.

Horse racing was the most popular entertainment of Qi nobles at that time. From kings to ministers, they often take pleasure in horse racing and gamble on winning or losing. Tian Ji gambled with the king and other ministers for many times. One day, he lost the horse race again and came home glumly. Sun Bin comforted him and said, "Take me to the racecourse next time. Maybe I can help you. "

Once again, Sun Bin followed Tian Ji to the racecourse, and civil and military officials of the Manchu Dynasty and civilians in the city also came to watch the fun. Bin Sun learned that everyone's horse is divided into upper, middle and lower grades according to the running speed, and the decorations of different grades are different. Every horse has different levels of races, and the races are the three best.

After careful observation, Sun Bin found that Tian Ji's horse was not far from other people's horses, but the improper use of strategy led to failure. Sun Bin said to Tian Ji, "General, please rest assured that I have a way to let you win." Tian Ji was very happy after hearing this, and immediately invited the king to race with his daughter as a bet. The king never lost a horse race, so he readily agreed to Tian Ji's invitation.

Before the race, according to Sun Bin's idea, Tian Ji decorated the inferior horse with the superior saddle and pretended to be the superior horse to compete with the superior horse of the King of Qi. At the beginning of the race, I saw the good horse of the King of Qi rushing ahead, and Tian Ji's horse lagged far behind. The king smiled proudly. In the second race, according to the arrangement of Sun Bin, Tian Ji used his first-class horse to compete with the king's middle-class horse. Amid cheers, I saw Ma Chong of Tian Ji in front of Wang's horse and won the second race. In the crucial third game, Tian Ji's Chinese horse competed with Wang's inferior horse, and Tian Ji's horse rushed in front of Wang's horse again. As a result, Tian Ji won the king by two to one.

The king, who had never lost the game, was dumbfounded. He doesn't know where Tian Ji got such a good horse race. At this time, Tian Ji told the King of Qi that his victory was not because he found a better horse, but because he used a trick. Later, he told the King of Qi about Sun Bin's plan, and the King of Qi suddenly realized that he immediately called Sun Bin into the palace. Sun Bin told the King of Qi that appropriate countermeasures can defeat the other side when the conditions of both sides are equal, but when the conditions of both sides are far apart, appropriate countermeasures can also minimize the losses. Later, the king appointed Sun Bin as a military adviser to guide the national army. From then on, Sun Bin helped Tian Ji to improve the fighting methods of the Qi army, which won many wars with other countries' troops.

Then there's the new Tian Ji horse race:

Tian Ji is a general of Qi. One day, he played with Qi Weiwang. They divided horses into three grades, namely, superior horses, medium horses and inferior horses. In competitions, they always use superior horses against superior horses, middle horses against middle horses, and inferior horses against inferior horses. Because all the good horses in the country are in Qi Weiwang's hands, Tian Ji lost three races. Although Tian Ji lost, Sun Bin found that Qi Weiwang's horse was not much faster than Tian Ji's in every race.

When Tian Ji was about to walk out of the racecourse, Sun Bin came forward and said, "Don't be sad, because most of the good horses in the country are concentrated in Qi Weiwang's hands. It's normal for you to lose, but ..." Tian Ji interrupted him impatiently and said, "I didn't expect you to satirize me!" Sun Bin said, "I think I can let you beat Qi Weiwang." Tian Ji looked at Sun Bin doubtfully and asked, "Do you want to change horses?" "You don't have to change a horse." Bin Sun said confidently. Tian Ji said confidently: "That's not the same loss!" Sun Bin told Tian Ji what he thought, and Tian Ji nodded. Therefore, they challenged Qi Weiwang again, and Qi Weiwang accepted the request without hesitation.

With a gong, the game started again. In the first race, Qi Weiwang sent excellent horses as usual, but Tian Ji used inferior horses against excellent horses in Qi Weiwang according to Sun Bin's plan. As a result, Qi Weiwang won the first game. After watching the first game, Qi Weiwang felt something was wrong. In the first race, there was not much difference between the top horses. Now, why did the gap suddenly become so big? Hmm! There must be some fraud, so Qi Weiwang called his groom and whispered a few words in his ear. The groom hurried away after hearing this. ...

At this time, Qi Weiwang proposed to have a rest before the game. Soon, the groom came back and whispered something in Qi Weiwang's ear. Qi Weiwang listened, nodded constantly, pondered for a while, and then said a few words to the groom. After a while, Qi Weiwang quietly announced that the game would continue. The second game has begun. Qi Weiwang asked Tian Ji to send the horses first, and Tian Ji sent the first-class horses to Qi Weiwang to compete with the middle-class horses. Qi Weiwang winked at the groom who was holding Qi Weiwang's inferior horse. Sun Bin blindsided and said to Tian Ji, "It's over! The trick was discovered! " Of course, Tian Ji won the game. In the last race, because Tian Ji only has medium horses, and the rest of Qi Weiwang are medium horses, you can know the result without comparison! Tian Ji and Sun Bin looked at each other, and then surrendered to Qi Weiwang.

Pretending to know nothing, Qi Weiwang asked Tian Ji, "What the hell is going on?" In desperation, Tian Ji had to say that this was Sun Bin's plan and laughed. "I knew you had used this plan! Let Sun Bin come out to see me. " Sun Bin and Qi Weiwang had a good talk after meeting, and Qi Weiwang was impressed by Sun Bin! Later, Tian Ji and Sun Bin were re-used.
