What events did the young Luban mainly talk about?

1, content: (1) Li Sandai, a young construction worker, was born in poverty. Before liberation, three generations of his family left their homes to beg, so they were named three generations. After liberation, he was determined to work hard and hoped to contribute to socialist construction. However, due to his low level of education, he often feels at a loss in his work. In order to improve their cultural level, Li San took an active part in evening classes and studied hard.

(2) Qin, site technician, college degree, evening school teacher. At first, she didn't like the clumsiness and stubbornness of the third generation students. Once, Mr. Qin asked three generations to do problems in front of the blackboard in class, but none of them could. The little fat man secretly handed the note to the three generations, and Mr. Qin misunderstood the three generations after discovering it. In addition, Korean technician Liang is biased against workers, saying that "workers learn culture and go in one ear and out the other". As a result, Mr. Qin's distrust of workers' learning deepened.

She was very touched when she saw that three generations were trying to solve a problem without considering tea and rice. Especially after listening to three generations of stories about his past sufferings, she was deeply educated and determined to help the workers learn culture well. Three years later, the education level of the third generation of Li has improved significantly. He studied Chairman Mao's works diligently, guided practice with Chairman Mao's thoughts, and achieved excellent results in production. Once, the construction team where Li Sandai was located undertook the task of the main structural column of the factory building.

(4) The task is required to be completed before the end of the month. In order to catch up with the time, three generations of Li racked their brains to come up with a quick and good quality method. He reformed a relatively backward working method in woodworking technology, "enlarging the sample", which was Li Sansheng's wish for many years. In order to realize his wish, three generations studied hard and tried again and again. The experiment failed because he neglected to learn from the old workers. In the experiment, he accidentally fell off the building frame and was seriously injured. Afterwards, at the accident inspection meeting, Li Sansheng took the initiative to take responsibility and check his mistakes in violating safety regulations. Master Gao and Qin also criticized themselves. Only Liang of South Korea maliciously attacked Li Sandai, thinking that he didn't respect his master and was a personal hero. Qin was worried that the third generation Li could not bear the excessive criticism from South Korea's Liang and others. After the meeting, she advised the third generation not to mind. Li Sandai is very calm about this. He feels that technological innovation will inevitably encounter some nails.

(5)1in the autumn of 960, after Li Sanhei was transferred to the site of the northern chemical fertilizer plant, he actively studied the reform "enlargement" while studying at the site. When the construction period was very urgent, he put forward his own innovation suggestions, which were immediately opposed by Liang and others in Korea. He believes that "enlarging the sample" is a practice handed down by ancestors, and no one has ever questioned it. Later, with the support of Chen, the third generation of Li successfully created a calculation table to replace the traditional "enlarged sample", which was recognized and praised by experts. After six years of study and work, the three generations of Li and Qin gradually deepened their understanding and feelings and fell in love sincerely.

2. Young Luban is a black-and-white film shot in 1964, directed by Shi Daqian. This film is unpretentious. It shows the growth process of a young worker with low education who loves technological innovation. It emphasizes his indomitable spirit of diligently improving his cultural level and overcoming difficulties under pressure.
