The hardest to bear Chinese characteristics:
1. Total indifference to the physical suffering of other people, particularly of animals.
2. High tolerance to pollution & littering.
3. Pronounced, “I’ll get all I can, right now..!” attitude.
With the shortage of women in China, it is easy to understand the incentives here. One of the fruits of Communism was that vodka is cheaper than safe drinking water. One of the fruits of that policy is that many Russian men are drunk much of the time and, compared to a rich Chinese man, not great marriage material.
That sums it up, nicely.
Another characteristic I've noticed is that they are not perfectionists like the Japanese. Japanese will seek perfection in engineering and work, while Chinese will settle for lower quality while getting the work done quickly. That explains a lot about shoddy products from China, the exception being robot-built items from western factories in China.
