Although this man is 80 years old, he is still full of energy when making a report, which makes people admire him. His students are all over the world. Chai Tianyou, another academician of Dongda University, is also his student. Automation expert in many universities in Shenyang, deputy director of Shenyang Institute of Automation, Chinese Academy of Sciences. It was he who walked in the forefront of China with Neusoft Automation, and he advanced with Neusoft teacher's thinking. It was his approachable and simple life that deeply touched me.

His thinking is very agile, as Professor Liu Jianchang from the School of Information of Northeastern University said: "Academician Zhang Siying is not satisfied with the goal of our school of information to strive for national first-class, but his goal is national first-class", and the master figure is just different.

A person's history is written by himself. Teacher Zhang asked us to remember the truth of "from good to bad". Don't live up to the good times, don't live up to your youth.
