A poem praised by later poets as a thorn in Su Qin's cantilever beam.

Among the Seven Heroes of the Warring States, Qin constantly sent troops to attack neighboring countries and occupied many places. The other six countries are afraid and try their best to deal with it. At that time, a man named Su Qin proposed "uniting" against the State of Qin, which means that the six countries unite against the State of Qin. Because the position of the six countries runs through the north and south, and the north and south are vertical, it is called "combination".

Su Qin is from Luoyang. Luoyang was the capital of the Zhou Emperor at that time. He wants to make a difference. He once asked to see Zhou Tianzi, but there was no way to introduce him. In a rage, he sold his property and went to other countries to find a way out. But he ran for several years and didn't become an official. Later, I ran out of money and my clothes were worn out, so I had to go home. The family saw him wearing sandals and carrying a broken bag, looking like a mess. His parents scolded him severely; His wife sat on the loom knitting silk without even looking at him; He begged his sister-in-law to cook for him, but she ignored him and leaned down and walked away. Su Qin was greatly stimulated and determined to take a breath. Since then, he has been eager to learn and study Sun Tzu's Art of War every day until late at night. Sometimes I study until midnight, and when I am tired and sleepy, I prick my thigh with an awl. Although it was painful, his spirit came and he continued reading. Legend has it that he tied his hair with a belt and tied it to the beam when he was studying in the evening. As soon as he dozed off, his head drooped, his scalp ached and he woke up. This is what people later called "hanging beam on the head and stabbing strands on the cone" to express the spirit of hard work. In this way, after more than a year of hard work, his knowledge is much richer than before.

Beginning in 334 BC, he went to six countries to lobby for the idea of "integration" and succeeded. The following year, the rulers of these six countries formed a vertical alliance. Su Qin hung the national seal of six countries and became a prominent figure.

The news reached Su Qin's hometown, and his parents, brother and sister-in-law all regretted their bad attitude towards Su Qin. I heard that Su Qin was going to Zhao, passing by Luoyang. The whole family rushed to the place 30 miles outside Luoyang, cleaned the road, prepared a sumptuous banquet, and knelt down to meet him. Su Qin saw this scene, before and after the contrast, mixed feelings.

However, Zonghe was quickly destroyed by Su Qin's classmate Zhang Yi's "Lian Heng" strategy, Su Qin was stabbed to death by an assassin, and Zonghe declared complete bankruptcy.
