Tie your hair to the beam and poke your thigh with an awl to stay awake ―― study hard/diligently.
Metaphor is to study hard and study hard. The story of "hanging beam" can be found in Taiping Jing (Volume 363) and quoted from Hanshu. During the Western Han Dynasty, there was a man named Sun Jing, a famous politician. At first, because of his shallow knowledge, he was not reused, and even his family looked down on him, which greatly stimulated him and made him determined to study hard. Often behind closed doors, reading alone. Reading from morning till night every day, often forgetting to eat and sleep. After studying for a long time, I am tired, but I still don't rest. After a long time, I was too tired to doze off. Afraid of affecting his study, he came up with a special method. In ancient times, men had long hair. He found a rope with one end firmly tied to the beam and the other end tied to his hair. When he is tired of reading, he dozes off. When his head is lowered, the rope will hold his hair and hurt his scalp, wake up immediately and continue to study. The story of "stabbing stocks" can be found in "The Warring States Policy Volume Sanqinyi". During the Warring States Period, there was a man named Su Qin, who was also a famous politician. When I was young, because of the lack of knowledge, I went to many places to do things and was not taken seriously. After returning home, his family was also very cold and looked down on him. This is a great stimulus to him. So, he made up his mind to study hard. He often studies late into the night, is very tired, often takes a nap and wants to sleep. So he thought of a way, prepared an awl and stabbed himself in the thigh when he dozed off. In this way, I suddenly felt pain, woke up by myself, and then insisted on reading.
