The famous allusion to encourage students to learn is the Ant Manor

Cantilevering beams and thorns are a Chinese idiom, which comes from "Taiping Yulan" Volume 363 quoted from "Hanshu" and "Warring States Policy·Qin Ceyi".

This idiom uses the story of Sun Jing's "head hanging from a beam" and Su Qin's "cone stabbing buttocks" as a metaphor for studying hard without eating or sleeping. Its structure is joint and can be used as an attributive in a sentence.

In ancient times, there was a sage named Sun Jing, who was named Wenbao. He loved learning very much and worked tirelessly. He would study non-stop from morning to night behind closed doors every day.

Sometimes it is easy to doze off in the middle of the night. In order not to affect his studies, Sun Jing came up with a way. He found a rope and tied one end to his hair and the other end to the beam of the house. If you are tired and sleepy from studying, your head will inevitably lower when you close your eyes and fall asleep. Then, the rope hanging from the beam will pull up your hair and hurt your scalp, and you will wake up due to the pain, so that you can continue. Reading. Later, Sun Jing finally became a famous bachelor at that time.

This is the story of Sun Jing's "hanging on the beam".

"Awl" tells the story of Su Qin.

During the Warring States Period, Su Qin's family was poor. He once studied with Gui Guzi, a famous scholar at that time, and learned a set of theoretical classics for governing the country and bringing peace to the world, and he wanted to serve the country.

At that time, King Qin Huiwen worked hard to govern and recruit talents. Su Qin should go and offer his plan for governing the country and bringing peace to the country. King Qin Huiwen failed to adopt his plan, and he had to return to Luoyang dejectedly. The parents at home sighed at him when they saw that their son had no future and could not even find a job, not to mention his wife, who sat on the spinning wheel and weaved cloth without even looking at him.

He was so hungry that he had to shamelessly ask his sister-in-law for a bowl of rice. His sister-in-law didn't have a good look on him either, and said sternly: "Where can we still eat? We don't even have firewood for cooking!" Su Qin almost shed tears after being refuted. He returned to his room, raised his head and sighed: "When a person is poor, his wife does not consider him a husband, his sister-in-law does not consider him a brother-in-law, and his parents do not consider him a son. What can I say!"

So he studied harder. When he felt sleepy while studying at night, he pricked his thigh with an awl to prevent him from falling asleep. The blood flowed all the way to his ankle. Of course, the pain was so painful that he couldn't sleep. Just like this day and night research, achievements were achieved in one year.

Finally, Su Qin finally became prosperous. His policy of unifying the world in Qin was not successful, so he immediately changed his policy and persuaded the six Shandong countries (Qi, Chu, Han, Zhao, Wei, and Yan) to unite. They rose up to form a "joint vertical" front, and they all resisted the Qin State and prevented the Qin State from leaving Tongguan.

Therefore, when Su Qin wore the seal of the Six Kingdoms and returned to Zhao from Chu, the honor guard was several miles long, with cavalry and infantry holding arms and shields, surrounding Su Qin's chariot, and in front of the chariot. Behind the car, flags covered the sky.

Special envoys sent by princes from various countries are sent with the festival, just like a monarch on a tour. When Su Qin's car passed by his house in Luoyang, Su Qin's sister-in-law, brother, and wife were so frightened that they fell to the ground and did not dare to raise their heads. The snobby look they had before was gone. After Su Qin returned to Zhao State, Zhao Suhou immediately named him Lord Wu'an.
