because the pronounciation of “送钟” is just the same as "送终“ which means attending one's funeral in Chinese. If you say to someone that 我给你送终，you mean I'm attending your funeral, which is very ominous in Chinese culture. And you should never give a green hat to a Chinese man as a present because in acient China, if you say a man is wearing a green hat, you mean that his wife is cheating on him.

i'd like to tell you that it's not good to cut the pear in two,and share it with your friends. it means you will part from your friends. "分梨" have the same pronunciation as "分离"

like knife, scissors ....this means cutting,,,,,,let people think cut the relation,,,,,,,,but in fact,,,,South Chinese maybe care about this,,,,,,most Chinese don't care,,,if some one sends me a clock,,,i won't feel unhappy too much,,,,,,,
