Since ancient times, China people have been very human, and they advocate caring for others. There is a famous saying in The Analects: "Don't do to others what you don't want others to do to you." It means that if you don't want to be treated like this, don't treat others like this yourself. What this sentence emphasizes is actually comparison. Taking care of your heart is a person's greatest kindness and accomplishment.
If a person can take good care of others, he can better understand the hardships of life, the hardships of life, and be more respectful and kind to others.
