1. Accumulate meritorious deeds over time, and cherish every inch of yin when there is no water. .

2. I think that people have two shoulders and should play a role at the same time. I want to carry the burden of door-to-door delivery with one shoulder and deliver scientific knowledge and tools to the workers' master. The other shoulder can be used as a ladder for young people to climb a higher level of science. .

3. Scientific achievements are accumulated bit by bit, and only by long-term accumulation can they be merged into the sea. .

4. Learning and research are like climbing a ladder. If you want to climb it step by step, you must be able to wrestle if you try to climb four or five steps with one foot and reach the sky on the ground.

. 5. Genius lies in accumulation, and cleverness lies in diligence.

. 6. There is no smooth road to science, and there are countless reefs and shoals in the long river of truth. Only herb gatherers who are not afraid of climbing, and only those who are not afraid of the waves, can climb the peak to collect fairy grass and go deep into the water to find pearls.

. 7. Independent thinking ability is very necessary for scientific research or any other work. .
