Why do many foreigners write with their left hands?

Recent research shows that the formation of left-handed people is related to the injury of pregnant women during pregnancy. No matter from what point of view, left-handed people are a minority on this planet, but few people say they are a vulnerable group. In fact, strictly speaking, being left-handed is also a derogatory term. One of the most intuitive problems for left-handed people is writing. The modern writing habit of Chinese characters is from left to right and from top to bottom, which is undoubtedly a great challenge for left-handed people. In ancient times, it was better. The brush is suspended, and the full text is written from right to left. Therefore, there were many left-handed calligraphers in ancient times, and Comrade Wen Zhiming in Ming Dynasty was one of them. As a senior left-hander, the author thinks that in addition to being easily seen through in words, in fact, left-handers still have many difficulties in the right-handed world. In China, when people find that a person is left-handed, they always mention "the cleverness of the left-handed". The logic comes from the fact that left-handed people often use their left hand and their left and right brains move at the same time. However, people also ignore the fact that the average life expectancy of left-handed people is much shorter than that of normal people. Apart from the unknown physiological reasons, personally, the biggest reason is the inconvenience in life. Most products are invented by right-handed, so the use of products conforms to the habits of right-handed, including the habits of most collective social activities, and the minority obeys the majority and follows the rules of right-handed. Therefore, we will often see that when eating at the round table, left-handed people will hold chopsticks to avoid "fighting" with the people on the left, while when eating at the square table, they will honestly sit in the left corner. Including the door handle, the direction of opening the door, everything needs left-handed people to constantly overcome difficulties. Some people may not understand why left-handed people are born in the world of right-handed, so they should get used to it gradually, but most of the things I have experienced personally are counterproductive. No matter what I learn, including billiards, tennis, badminton, guitar and violin, it is definitely the opposite of right-handed. One of the signs of social modernization is to pay attention to the living conditions of various vulnerable groups, so the large number of left-handers in the west is not that the proportion of left-handers is rising, but that they can stretch freely. All vulnerable groups need social care.
