How to distinguish Asians?
Koreans: Koreans don't show the Asian-specific formality in a strange environment, but appear arrogant. This is because of the long-standing habit of national inferiority complex, which aims to cover up one's inferiority complex, but in a familiar environment, in front of familiar people, it will appear very stiff.
Japanese: In Asian countries, it is difficult to tell whether a person is a local or a Japanese. Japanese people usually learn from people around them, which depends on their unreliable figure, not their height. Now, the average height in Japan is higher than that in China. The biggest feature of the Japanese is to bow their legs. It should be easy to tell the difference between walking posture (outside the eight characters) and the habit of nodding and bending when talking.
Southeast Asians and southerners in China are not much different, but because they are located near the equator, they have strong ultraviolet rays and are grayish black.
Most people in Central Asia, West Asia and South Asia are white or white and yellow, which can be seen at a glance.
