Mencius said

Mencius said, "There is nothing more than ignorance of the king. Although there are things that are easy to live, if it is violent for one day and cold for ten days, no one can live. I think it's rare. All the ones that have cooled down are here. If I am cute, what can I do? The number of games played today is decimal; You can't do it if you don't concentrate. Qiu Yi is the best athlete in this country. Let Qiu Yi teach two people to play chess: one person concentrates, and Qiu Yi listens; Although a person listens, he thinks that the swan is coming and wants to pay for the bow and shoot it to death. Although he learned from it, it was impossible. Is it because his intelligence is not as good as the former? That's not true.
