Zuo Tangzong once said: "It is better to raise your heart than your mouth." The meaning of this sentence is: it is better to cultivate one's self-cultivation than to pay attention to food and clothing. Do things for people, be fundamental, and get rid of glitz. It is better to build the soul than to pursue material life. In Zuo's original words, there is a difference between nourishing the mouth and the heart, and nourishing the heart is more important.

There are two kinds of filial piety, one is to raise the mouth and the other is to raise the heart. The so-called support is to be around your parents, to have food and clothing, and to raise your heart is to get ahead and let your parents have face. When you are young, you may think it is more important to "cultivate your mind", which not only makes your family face, but also enriches your life and improves your ability. However, when you get older, you may feel that "keeping your mouth" is more important. The best day is the one with family.
