It is to choose the advantages of others to learn and pay attention to correcting your own shortcomings.

The phrase "choose good and follow it" shows the spirit of Confucius' self-cultivation and humility. It includes two aspects: on the one hand, it is the spirit of being open-minded and eager to learn; On the other hand, people who have not changed well should take warning from their shortcomings and reflect on themselves. This is the spirit of self-cultivation. In this way, no matter how good or bad people get along, they can be teachers.
