Liu Jia's "cow" partly stems from his special personal experience.

Liu Jia, who was only interested in mathematics, began to teach himself college mathematics textbooks in high school. When he was at school, he often taught math problems to his classmates, which shows his extreme love for math. But only mathematics outshines others, and Liu Jia feels that going to college is hopeless. 1987, he chose to drop out of school when he was a sophomore, and then he became a substitute math teacher in primary school and went to work as an electrician in the factory. His colleagues' children often came to him to ask math questions.

At this time, the extracurricular training market began to sprout. Liu Jia often takes part-time classes outside after work or at night to train mathematics. Because of his minor fame, he was later attracted by a teacher surnamed Ke in the teaching and research section of Jiang 'an District, and was recruited to be a temporary teaching assistant in Jiang 'an Olympic Mathematics School specially set up for the mathematics competition, and he embarked on the road of education and training.

Liu Jia recalled that in the years of 1990, the education department supported Olympic mathematics training and competition as a way to cultivate students' hobbies, and it was very easy to enter key middle schools after winning the mathematics competition. Liu Jia thus gained a lot of living space.

As a temporary teacher, Liu Jia has been engaged in mathematics training in many primary schools. He described himself as "running like a singer". From 8: 00 in the morning until evening, he goes to a school every morning, afternoon and evening to give lessons to students who are ready to take part in the competition. The school math teacher mainly talks about the content of teaching materials, and Liu Jia is responsible for broadening and upgrading the knowledge points of the school.

From 65438 to 0994, Liu Jia decided to get rid of the dependence on public primary schools and recruit students independently. He printed many advertisements for psoriasis and posted them everywhere to attract students. As a result, he was reported as "running a school in violation of regulations".

Before investigating him, the relevant departments learned that he was only a high school dropout and were taken aback: "Isn't it harmful for dropouts to come out to teach?" But because of the fame and connections accumulated in the training market, Liu Jia finally got a legal training license. After many twists and turns, in 200 1 year, he formally established "Mingxin Education and Training Center" and registered Mingxin's trademark in the Industrial and Commercial Bureau.

When asked about Liu Jia's personal income, he didn't say it explicitly, but euphemistically said that the income of teachers who teach here is at least twice that of other famous teachers. It is understood that "Mingxin" offers four courses every year, and each student charges six or seven hundred yuan. About 70% students usually attend all four courses.

Liu Jia said that such a successful experience is almost impossible to replicate now. According to his education, he can only do odd jobs at school at most.
