Is the ancestor's ability to recognize people accurate?

Communication between people is inevitable. Everyone will inevitably have contacts with others, and it is inevitable that they will meet all kinds of people in their contacts. So how do we identify these people? The ancestors left such a sentence, with thin lips and small jaws. So what exactly does this sentence mean?

Your lips are too thin to make friends. The first half of this sentence says that people with thin lips are generally fickle and cannot make friends. This sentence is actually a typical judge by appearances. Is thin lips necessarily fickle? No, thin lips can also refer to a person who is cynical and adds fuel to the fire. Such people have many negative emotions and are outspoken. What they should say and shouldn't say will be poured out with bamboo tubes and shaken out in a lot. If you associate with such a person, some secrets or just two people's jokes will be inadvertently said. To associate with such a person is to plant a time bomb. Lao Tzu said in the Tao Te Ching that it is better to talk more than to count the poor. Guiguzi also said that many words have shortcomings and thin lips. The appearance of thin lips is to warn people to know how to protect themselves when they meet people who can speak eloquently. Don't be blinded by sweet words, which will affect the judgment ability of brain thinking.

The mandibular tip is small, and the mandibular tip also refers to the chin. According to ancient physiognomy, Fiona Fang people are generous, kind and rich, and they are excellent friends. On the contrary, if the chin is pointed, you will not have such a big mind, and you like to haggle over every ounce on weekdays. When interacting with people, I always want to get the upper hand and don't allow myself to lose to others in words and attitudes. However, if a person's chin is still flat, it is obviously inaccurate to comment on his character or temper. After all, a person's appearance and inner world are sometimes two extremes. Some seemingly vicious people may be very soft inside. On the contrary, people who seem kind may not be ruthless. The reason why the ancestors said this is to warn everyone that if a person is narrow-minded, he will lose the pattern. Without the pattern, people can't achieve great things.
