Smiling
People smile at times. However, the meaning of a smile in different cultures may be different. Depending on different cultures, smiling can express joy and amusement, but it can also indicate embarrassment(苦恼). The following examples show this point of view:
In an attempt to be open and friendly, people in the United States smile a lot. Every one smiles at each other, this nonverbal communication shows being friendly in the United States. However,in China, smiling is not only an expression of happiness, but also a way to avoid being embarrassed. Chinese people like smiling when they are embarrassed in order to avoid embarrassment. Smiling is a kind of good will but not sneer(嘲笑). For example: When a child falls off from a bike, the adults in China may smile, which is a kind of gentle encouragement and may not be a kind of impolite laugh.
When a person from the United States might blush(脸红)with embarrassment or become offensive, a Chinese might blush with smile. To avoid serious misunderstanding, people who engage in intercultural communication should be able to understand the meaning of smiling appropriately. Related to the smile is the laugh. Also, different cultures have different meanings about laugh. For example, Americans can enjoy a very heartfelt belly (腹部) laugh that comes from the deepest emotions. However, most Chinese seldom laugh that way because they are thought to be silly except among close friends.
