1. He who knows the current affairs is a hero, but he who does not know what is going on is not a wise man.

2. "A gentleman can bend as well as stretch."

3. Simple advancement and retreat will only give us extremely one-sided consequences. Only by recognizing the current situation and correctly handling the dialectical relationship between advancement and retreat can we live better in the world.

4. He who only advances without retreating is a reckless man.

5. History has passed, and now it has just begun. If you do not make progress as a means of advancement, and do not use retreat as a retreat, you will be a hero if you understand the current affairs correctly.
