1, pulse condition influence theory of traditional Chinese medicine.
The meridian mentioned by TCM is no stranger to everyone in China. Chinese medicine believes that there is a part called "Cunkou" on a person's wrist, which connects the three points of the human body "Cunguan-Chi".
2. Habit decides to say.
The above-mentioned influence of pulse condition in traditional Chinese medicine seems to be just a general statement. In fact, watches have little effect on our health. And more often, people will decide which hand to wear according to their own habits. Many friends wear watches on their left hands for convenience, but a few "left-handers" like to wear bracelets on their right hands.
3. Practical decision theory.
Most male friends will put their hands on their left hand, because the right hand is used for work and they don't like the uncomfortable feeling at work. Moreover, watches worn on the right hand are not allowed to look at the time, and they must be corrected with the left hand to see the time. Generally, boys' watches are not necessarily luxurious and exquisite, but they must be durable and keep good time.
4. Traditional influence theory.
China has a saying that the left side is big and the right side is small since ancient times. Seats during the festival are also arranged in this way. Perhaps for this reason, many people like to wear watches on their left hands.
1, the working principle of a watch. A watch is a precise instrument used to indicate time. The principle of this instrument is based on a vibration system with constant period and continuous vibration.
2. If we know the time required for the vibration system to complete the whole vibration of a watch (vibration period) and calculate the vibration times, then the time after vibration for so many times is equal to the vibration period multiplied by the vibration times. That is, time = vibration period × vibration times.
