Six Chinese Characters

Dear students,  our country has a long history.  Chinese characters usually have more than one meaning and some of them are particularly loved by Chinese people.  Here are the top six lucky ones.  Please note we use "pinyin" here because "pinyin" is the Chinese spelling system for the characters. For example, "fu" is the "pinyin" for good luck in Chinese.  "pinyin" "fu" is only the phonic   (语音的 )  part of the character and if you want to know the meaning of good luck "fu",  you must read the Chinese character福 because "fu" also represents  (代表)  other Chinese characters that sound the same.

1.福  "fu" means blessing,  good fortune,  good luck. Chinese character福 "fu" is one of the most popular ones used during Chinese New Year. It is often displayed upside down on the front door of a house or an apartment.  The upside down福"fu" means good luck comes since the character for upside down in Chinese sounds the same as the character for "come".

2.禄 "Iu" means prosperity.

It is used to mean official's salary(薪水 ) in feudal (封建的 ) China.

3. 寿 "shou" means longevity.

Chinese character寿  "shou" also means life,  age or birthday.

4.喜 "xi" is happiness.

The doubled character喜 "xi" means double happiness. It is usually displayed everywhere at Chinese weddings.

5.财  "cai" is wealth or money.

Chinese often say "money can make a ghost turn a millstone". It is to say money really can do a lot of things. But, still-money can’t buy everything.

6.和  "he" means harmomous.

People's harmony is an important part of Chinese culture. When you have harmomous

relations with others,   things will be a lot easier for you.
