Case:

Dongxie worked in a multinational company in the United States and he came back to China for a vacation. When he went back to his company, he paid the manager a visit and presented him a gift. The manager opened the gift. It was a ginseng人参 with its many roots spreading out in a very artistic pattern. It clearly was an expensive gift. The manager's eyes shone at the ginseng, but then he began to feel uneasy. " Dongxie, I appreciate your kindness, but I cannot take this as a gift."

•            " Why? Don't you like it?" Dongxie became uneasy now.

•            "Oh, sure, I love it. But I cannot accept it."

•            "Why?"

•             "Because I don't do anything to deserve it."
