What contribution did Sun Bin make to China after he became a strategist? A: After Sun Bin arrived in Qi, his main achievement was that he defeated Wei and helped Qi lay the foundation for hegemony. It was the Warring States period, and Wei was the overlord at that time. Sun Bin was invited by his classmate Pang Juan to be an official in Wei. Later, he was framed and tortured by Pang Juan, and his foot was broken. After Sun Bin was rescued by the emissary of Qi, he helped Qi win the battle of Guilin and the battle of Maling, wiped out the main force of Wei in one fell swoop, made Wei lose its hegemony and laid the foundation for Qi's hegemony.

When Sun Bin arrived in Qi, he bathed and changed clothes, taking on a new look. The King of Qi has long known Sun Bin's name, and now it's really a brief encounter. At that time, he would disregard the etiquette that a "criminal" should not be an official for life, and give a generous salary to a senior official in Sun Bin. Sun Bin said, "No, Your Majesty, I can't be rewarded because I have no credit. Moreover, if Pang Juan knew I was alive, he would definitely attack Qi. Why don't you allow me to hide it? When something happens to the country, I will try my best. " The King of Qi agreed.

In 353 BC, an army led by Pang Juan surrounded Handan, the capital of Zhao. Send someone to ask Qi for help. The King of Qi asked Sun Bin for advice, and Sun Bin thought that he should send troops. The King of Qi wanted to worship Sun Bin as a general and lead troops to save Zhao. Sun Bin said, "I'm a criminal, and I'm afraid I'll lead my troops and humiliate the king. I'd better ask Dr. Tian Ji to be a general and I'll help him. " The King of Qi worshipped Tian Ji as a general, and Sun Bin led the troops to save Zhao.

Sun Bin suggested to Tian Ji: "I guess Zhao is no match for Pang Juan. If Zhao is rescued as planned, I'm afraid Handan will be breached by Wei Jun before we reach it. Why don't we make a diversion and directly attack Anyi, the capital of Wei? In this way, Pang Juan will return to the army for rescue, and then we will ambush halfway and take Pang Juan by surprise. It can not only relieve the siege of Zhao, but also blow the arrogance of Wei and reduce its threat to Qi. I wonder what the general thinks? " Tian Ji said, "mr. yi."

Pang Juan surrounded Handan, and when he was proud, he suddenly heard that Qi had attacked Anyi. Pang Juan one leng, I didn't think qi will be in possession of the master, come up with such a coup. He didn't leave the army to rest, and hurried back to the division for rescue. It is said that the capital is in danger, and everyone in Wei Jun is uneasy. In addition, after several days of fighting, the troops did not rest. At this time, Wei Jun, aided by Huiyuan, was disheartened and demoralized, like a failed teacher.

It's easy to return to Wei, and it's not too far from the capital. Pang Juangang wanted to catch his breath, but he was ambushed by the Qi army in Guiling. Due to an accident, Wei Jun was unprepared and was defeated by the Qi army. When Pang Juan was defeated, he was startled to see the big word "Sun" on the flag of the Qi army in the distance. He asked, could it be the cripple? ! Therefore, the withdrawal is imminent. After Pang Juan's defeat, he made many inquiries, knowing that Sun Bin really worked in Qi, and he was fooled. At that time, he didn't dare to commit himself to Qi easily.
