Confucius studied diligently throughout his life. In his later years, he especially liked the Book of Changes. The I Ching is difficult to understand and difficult to learn, but Confucius was not afraid of hardship and read it over and over again until he understood it. Because in Confucius' time, paper had not yet been invented, and books were written on bamboo slips or wooden slips, which were bulky and heavy. Many bamboo slips were woven together with leather strips to form a book. Because Confucius studied hard and displayed his slips so many times that his leather strap was broken three times. Later, people coined the idiom "Three Wonders of Wei Bian" to convey the diligent and studious spirit of Confucius

It was late at night, and the sound of reading suddenly came from the Buddhist temple. The young monks were frightened, thinking there was a ghost inside, and immediately reported it to the old monk. So the old monk led the young monk to catch ghosts. Unexpectedly, the "ghost" turned out to be a poor boy named Liu Xie, who was borrowing a Buddhist lamp to study. After studying hard, Liu Xie finally became a great literary theorist.

The mathematician Hua Luogeng has a unique way of reading. Every time he reads a book, he doesn't read it from cover to cover as soon as he starts it. Instead, he closes his eyes and meditates on the book, guessing what is written in the book. After thinking for a while, open the book. If the content of the book is consistent with his guess, he will stop reading; if it is different from his guess, he will read it seriously. Hua Luogeng's "guessing reading method" not only saves reading time, but also cultivates his thinking and imagination abilities.

Hou Baolin, the language master, only went to elementary school for three years. Because of his diligence and studious, he finally became a famous cross talk artist.

On the evening of October 19th. Huang Jiguang's battalion was ordered to counterattack at Highland 597.9 on the right side of Shangganling. The 6th Company was ordered to seize Position 6 in advance, and then Positions 5 and 4. Position 0 must be captured before dawn to lay the foundation for the victory of the entire counterattack. Once the battle began, it went more smoothly than expected. At this time, it was suddenly discovered that there was an enemy group firepower point on the top of the mountain, which suppressed the volunteer troops and prevented them from advancing. The battalion chief of staff immediately ordered the 6th company to blow it up and organize a demolition team. From 7:30 p.m. to 10:30 p.m., the 6th Company had launched five charges against the enemy, but the enemy's firepower was still not destroyed, and many soldiers died heroically. At this time, there were only more than 40 minutes until dawn. Failure to capture position 0 would mean that the combat mission had not been completed as planned, and the victory of the entire counterattack would be affected. At this critical moment, Huang Jiguang, who was standing next to the chief of staff, stood up and demanded firmly: "Give me the task. As long as I have breath, I promise to complete the task." The chief of staff said with great confidence: "Huang Jiguang, this mission Leave it to you, now I order you to be the acting squad leader of the 6th Squadron of the 6th Company. You must complete the mission!" After accepting the mission, he immediately put on the grenade and led his two comrades to crawl towards the enemy's firepower point. They took advantage of the bright light of the flares and advanced skillfully. The enemy did not notice them at first. When they were only more than 30 meters away from the enemy's fire point, two comrades fell one after another. Huang Jiguang's left arm and left shoulder were shot twice, and he was bleeding profusely, but he still kept moving forward toward the enemy's central firepower point. When there were only eight or nine meters left, he puffed out his chest and raised his right hand to throw a grenade at the enemy. However, due to the excessive firepower, only half of it was blown up. The two machine guns that were not blown up were fired from the remaining shooting holes. Stretching out, roaring desperately, the charge of the volunteers was blocked again. Huang Jiguang was injured again and fell down. At this time, the sky was about to break, and the 40-minute deadline was about to come. Huang Jiguang jumped up, pointed at the muzzle of the gun that was spitting out tongues of fire, and pointed at the stubborn fortress of the invader. He puffed up his chest, opened his arms, and pounced. Go up... The flames that were spitting out suddenly went out, and the roaring machine guns became silent. Huang Jiguang used his young life to open up the path for the volunteers to advance successfully
