First of all, it should be a genetic issue. It is said that if the parents are all right-handed, the chance of giving birth to a left-hander is only 2%. Even if all the parents are left-handed, the chance of giving birth to a left-hander is only 5%. The probability is 10, so there will be fewer natural left-handers than right-handers.
Then there is the social aspect. Most people do not recognize the term right-handed. Because the right hand is the majority, it is normal, so left-handed people are abnormal. In ancient times, there were also people who moved to the left and had different opinions. , the saying of left-wing doctrine, and some people's way of saying right, so left is a deviation. Although the saying of left and right is different in different dynasties and generations, the wording has not changed.
Also, in terms of utensils, everything is made for right-handers. Scissors are probably the least likely to be used by the left hand. I have tried and can’t cut anything at all. I have seen others use chopsticks and pens. The left hand, but to develop this habit, you need the support of your family, no objection from your deskmates, and the ability to withstand strange looks. Xiao Zisheng in "Cha Classmate Boy" can write with both hands, and both are calligraphy with a brush.
As for the family, there is a rumor among our parents that being left-handed will affect your speech, and may even cause you to be unable to speak at the age of three or four. I don’t know if it is true or not. It is said that when I was a child, I tried to use my left hand. I was beaten to change my use of chopsticks. Now I am semi-left-handed, or fake left-handed. I also use my right hand for many things that were originally invented for right-handers, such as mobile phones, chopsticks, and pens, but I use my right hand when applying force, opening and closing doors, lifting things, etc. I am still good with my left hand in small movements. I am used to using my left hand when playing table tennis. As a result, my classmates always couldn't catch the ball and stopped playing with me. As for the rumor that left-handers are smarter, I think it is wrong. I am not smart at all. On the contrary, they are too stubborn and too straightforward. Although there are many left-handed celebrities, such as Marie Curie, Obama, Bill Gates, Einstein, Napoleon, Newton, etc., there are also many right-handed celebrities, right?
