Generally speaking, human feet can be divided into three types, namely Egyptian foot, Roman foot and Greek foot. Among them, the Greek foot is a type of foot whose second toe is longer than other toes, also called Morton toe, which is an abnormal manifestation of the forefoot. The reason for this phenomenon may be the poor stability of the foot, so the second toe should protrude and bear enough strength to help the stability of the foot.

Therefore, what people's toes look like is related to their own race and heredity, and also to the influence of the acquired living environment, but it has nothing to do with people's filial piety. Whether a person is filial is related to his living environment and education, to the feelings between people and to his moral quality.

Therefore, don't blindly accept some old sayings and sayings about abortion in ancient times because of the life experience of the ancients. We should know that there are still some dregs handed down from them that need to be eliminated, eliminated and changed.

In the past, people often judged a person's personality by his physical features, his fate by the lines of his fingers, and his personality by his five senses. I used to listen to palm reading the most. In fact, there is another feature that can judge a person by the shape and length of his toes.

So what does the subject mean by "two thumbs and toes are long, and when they grow up, they don't adopt their mother"? Is it reasonable? What I have heard most before is that some elderly people will judge a person's life by the shape of their thumb. If his thumb is big, thick and flat, then this kind of life may be what people often say. Generally speaking, the thumb bears the most gravity. If you do hard physical work for a long time, your figure will become flatter and flatter.

Although this seems reasonable on the surface, in fact, it is totally unrealistic for us to explain it in a scientific way. The shape of a person's feet and thumbs is mainly determined by genes. Some people are caused by heredity, and the acquired influence is a small factor, so personally, it doesn't make much sense.

Let me talk about the second toe. There are generally two kinds of toes. One is that the little toe is getting longer and longer, and the other is that the second toe is obviously more prominent. This is called the second toe length. This sentence means that if a person has two long thumbs, it means that such a person is unfilial, regardless of his parents when they are old, and has no filial piety. However, this concept is incorrect and has no scientific basis at all.
