I learned this through my own experience. Last weekend, Wang Lin and I showed two foreigners around our city. Mr. Singh was from India and Mr. White from the USA. When I held out my left hand to shake hands with him, Mr. Singh seemed to be unhappy. Mr. White, however, was quite casual (随意的). He said hello to me with a big smile and a wave of his hand. In the evening, we stopped at a restaurant for dinner. I noticed that Mr. Singh didn't touch the beef and Mr. White seemed not to like chickens' claws(爪子). During the meal, Wang Lin said sorry to Mr. Singh and continued to explain that we didn't know it was a taboo in India to shake one's left hand. Mr. Singh explained that since oxen (牛) are sacred (神圣的) in India, people don't eat beef there. Mr. White joined in and said that it was not usual in the States for people to eat chickens' claws. He went on to say that Americans don't usually get into each other's personal space. Isn't it a good lesson to remember?
