First,? I think this is because my teacher taught me how to be a man when I was seriously ill, and let him know what kind of person to be. It can be seen that Laozi's teacher attaches great importance to Laozi, and Laozi studies hard with his teacher. He can humbly ask the teacher for any questions that the teacher can answer for him. This also shows that the teacher attaches great importance to Laozi, so Laozi went to see the teacher when he was seriously ill, and the teacher also taught him what to pay attention to when he was a man.

Second,? Teacher's teachings

I always speak German. I said I had to get off when I passed by my hometown. Do you remember? Laozi replied that getting off at home is to ask us not to forget the past days. Changzong said he was right. He said he would win if he saw the tree. You got it? Lao Tzu replied that it was enough for us to see Qiao Mu win, and the manager always said that's it.

Changzong opened his mouth to Lao Tzu and asked me if my tongue was still there. Lao Tzu said, of course, I was in Changfeier, and I asked my tooth that was still smiling in my head, and it was long gone. Chang Fei-er then asked Lao Zi, Do you know what the reason is? Lao Tzu replied that the tongue can exist because it is soft, so it can survive, and the tooth does not exist because it is too stiff, so it is lost. Changzong was satisfied with Laozi's answer and said that the answer was good. Well, everything in the world is tolerable. What else can I tell you? That's why I became a master.

Changzong made Lao Zi understand through his words and deeds that the tongue died of teeth, and the teeth were tied to the tongue, but it was closed first, and the tongue was softer than the teeth and lasted forever. Later, Lao Tzu wrote down the softest and most powerful feelings in the world in the Tao Te Ching.
