Zhang Weisheng is 24 years old this year. He has just graduated with a doctorate and is staying at the school to teach. His research direction is Marxist philosophy. Why did you choose such a major? In the words of Zhang's father, Xiaosheng went to college at the age of 16. It is easy for a person to learn bad things outside. The key to learning Marxism is to let Xiaosheng take the right path in thinking and establish a correct outlook on life, so that he will not make big mistakes in the future. Many years later, Zhang's father felt that the decision he made for his son was wrong. His son was decent, but he couldn't stand up to bad people. In fact, Zhang's father still doesn't understand his son, nor does he understand the great power of Marxist philosophy!
