Description: After more than half a century, I have experienced three regime changes. I suddenly look back. Qingzhou has passed the Wanzhong Mountains. What is left to future generations is the scholarly style of worrying about the country and the people and the ardent hope for the country's development. This book brings together the life experience and insights of Professor Li Jiatong. He has seen many unfavorable situations for the country in his life, but he has survived every time. The reason is that the country's efforts to improve industrial standards have transformed us from an agricultural country to an industrial country. At that time, the country's approach was very down-to-earth and did not hit high altitudes at all. This is true not only in industrial development, but also in education.
