1. Playing with people loses morality, and playing with things loses morale. The ambition is peaceful with the way, and the words are connected with the way. ——"Shang Shu"

Taking pleasure in teasing others is a sign of moral corruption. If you become too obsessed with something, you will lose your fighting spirit. One's own will must be in line with the Tao in order to be at peace, and other people's speech must also be in line with the Tao in order to be accepted.

2. Private viewing makes the eyes blind, private listening makes the ears deaf, and private worries make the heart crazy. ——"Spring and Autumn"

If you look at problems with selfishness, you will not see anything; if you listen to problems with selfishness, you will become deaf; if you think about problems with selfishness, you will make your heart confused. Madness has no rules.

3. The heart is full of desire, and the earth behind it is hard to fill. ——"Mandarin"

Once a person is controlled by desire, desire is like an abyss, unfathomable, and no amount of things can fill it up. It will lure you step by step towards the abyss.

4. When the sun is at noon, it will move, when the moon is full, it will be waning, and when things are prosperous, they will decline. ——"Warring States Policy"

The sun will shift after noon, and it will be waning after the full moon. Once anything becomes too prosperous, it will decline.

5. My heart is so fragile that I cannot change it. My heart is so powerful that I can't take it away. ——"The Book of Songs"

Love and marriage require loyalty. The reason why oaths are called oaths is because they cannot be changed easily.

6. The difficult things in the world must be done in the easy way; the great things in the world must be done in the details. ——"Tao Te Ching"

The difficult things in the world develop from easy times, and the great things in the world are formed step by step from small places.
