I don't know how to find reasons for myself to say that other people's poems are not good.

For example:

1. If you want to add a crime, you can always find it!

Think more about yourself when you have time, and don't discuss the right and wrong of others.

Don't do to others what you don't want them to do to you.

It is good to know your mistakes and correct them.

The crow stands on the pig, only seeing others black, but not seeing himself black.

6. pot calling the kettle black.

Interpretation of Ancient Chinese: pot calling the kettle black, during the Warring States Period, Quan Mencius talked with Liang and made an analogy. Two soldiers were defeated at the front. One escaped fifty steps, the other one escaped a hundred steps, and the one who escaped fifty steps laughed at the hundred steps and said he was useless. In fact, both of them are running, just running far and near. Metaphor means that you have the same shortcomings or mistakes as others, only to a lesser extent, but you laugh at others.
