As soon as Putin became president, everyone noticed that his watch was worn on his right hand. Why? After studying a large number of books on oriental medicine, Russians have come to the conclusion that President Putin's habits are related to the ancient fitness system in China. -Inch mouth is related to health. Chinese medicine says that there is a part called Cunkou on a person's wrist, which is connected with three pulse points of the human body. These three acupoints have a great relationship with human health. They are distributed in the wrists of the left and right hands, under the thumb. When China people feel the pulse, they only need to press (sink), middle press (middle press) or light press (float) these parts again, and hold the pulse point with their forefinger. It takes only a few tens of seconds to get everything you want to know about your physical condition and measure the internal organs. Ancient medicine in China believed that the "inch-to-inch" part contained the secret of health and success in life. When the pulse is clear, even and strong, it shows that people are energetic, cheerful and tenacious. The most critical part is "inch", because it corresponds to the condition of "heart". -Men and women wear watches in different ways. Interestingly, the key points of male and female pulse phase are distributed in different hands, the man's left hand and the woman's right hand. The medical profession believes that the reason for this phenomenon is that men's blood flows from the end of the heart to the left, while women do the opposite. From this, an important conclusion is drawn: if a man wears a watch with his left hand, no matter what material the strap is made of, such as gold, silver, plastic or leather, it will affect the normal work of the heart, while a woman is lucky and does not need to change the habit of wearing a watch with her left hand. Russians believe that China's ancient "life" theory includes five systems: fitness, judo, meditation, diet and astrology. Fitness is the most beneficial to people, it can relieve the high tension in life. Monks in Shaolin Temple practice in this way. If people want to practice completely according to China's ancient theory of "destiny", they should start from the wrestling in the East, which is widely used in China, Japan, Viet Nam and North Korea. Putin wears a watch in his right hand and likes judo, which seems to be influenced by China's traditional health theory. I think there should be no difference between the left hand and the right hand. But judging from the habit of the dominant hand, the watch should be worn on the wrist that is not commonly used, because it is often used by the dominant hand, and it is likely to cause inconvenience if the watch is worn on the dominant hand.
