During World War II, how did Americans who helped China distinguish between China and Japanese?

There are special instructions to distinguish between China people and Japanese people, or according to our own experience.

Since the United States declared war on Japan from 194 1, it has been providing non-stop assistance to its allies, including China. China, as the main battlefield in the East, is highly valued by the United States, so it not only provides materials, but also a large number of technicians and combatants. The most famous one is the Flying Tigers led by Chennault, but it has become a big difficulty for Americans to distinguish China from Japanese. Later, after a quick investigation, the relevant departments of the United States published a booklet on how to distinguish the two countries, which contained detailed records, which was more in line with the appearance and even behavior habits of the two armies at that time.

The whole booklet * * * 75 pages vividly introduces the differences between the two countries to the US military in the form of cartoons and words:

Pathology/physical signs

According to the manual, China people are much taller than Japanese people, close to Americans, with long and thin legs, while Japanese people are really better than China people and look short but thin.

situation

China people's skin is dark brown, which is actually very close to the yellow skin of China people we are describing now, while Japanese people are darker.

Walking mode

According to records, this is a very effective method, because due to the huge deviation of lifestyle, Japanese people often wear clogs, which makes them feel like dragging things, while China people hold their heads high and walk steadily.

accent

This is really powerful, because people's appearance is different, it is really difficult to distinguish, accent is the distinction of racial characteristics, it is difficult to change. It is recorded in the manual that Japanese people don't pronounce S, and they tend to procrastinate, which is easy to distinguish.

However, after all, what is in the manual is still in the manual, not practical. To really distinguish it, you need the baptism of war and your own deep thinking and research to finally find it.
