This sentence is the mantra of a graduate math teacher named Zhang Yu. The teacher's lectures are humorous. He likes to say push this mantra right away. "Put off the postgraduate entrance examination immediately" probably means that if you can't understand such a simple topic, don't take the postgraduate entrance examination. Then there is usually an encouraging word, "Don't give up, it's a pity to give up, you see how simple this problem is."

Zhang Yu, a graduate mathematics teacher, has been engaged in advanced mathematics teaching and postgraduate counseling for many years, and has published many papers in national core journals, one of which was selected for the "2007 Global Sustainable Development Conference". His representative works are:

1, Advanced Mathematics Lecture for Postgraduate Entrance Examination 18, Zhang Yu Linear Algebra Lecture 9?

2. 9 lectures on probability theory and mathematical statistics for postgraduate entrance examination?

3. One's deceased father grind mathematics problem source classic 1000 problem.
