The parenthesized entries are the complex and formal forms, which are used mainly in notarized, official documents, and when writing checks. An exception is zero; the complex form is much more widely used than a casual circle. The complex forms are known in English as banker's anti-fraud numerals, in Chinese as 大寫 (simplified Chinese: 大写; Hanyu Pinyin: dàxiě; which is the same term for "capital letter"). They are necessary because, since normal Chinese characters are so simple, a forger could easily change 三十 to 五千 with just three strokes. See Standard numbers for more information.

Some Chinese characters used as complex and formal numerals have other uses as well, possible as heteronyms. For example:

• 貳èr can also mean "to betray".
• 肆sì can also mean "to be impudent".
• 伍wǔ can also mean "military" figuratively and be a surname. It can also mean "line" when said as "队伍"
• 陸 means six formally when pronounced liù, but "land" or a surname when pronounced lù.
• 拾shí can also mean "to pick up".

中文中零的用法 The Use of Zero in Chinese

If a number ends in zero, there is no need to include the Chinese character for zero. For example,

• 350: 三百五十
• 1350: 一千三百五十
• 1600: 一千六百

However, if the zero character does not end the number (i.e., it is followed by a non-zero character), it is necessary to include the zero character, while the "tens-place" characters are dropped. For example,

• 305: 三百零五 (not 三百零十五)
• 1035: 一千零三十五 (not 一千零百三十五)

Note that the "十" in the first example and the "百" in the second example are dropped.

If a zero digit is followed by one or more zero digits, only one zero character is need. For example,

• 1006: 一千零六 (not 一千零零六)
• 300,250: 三十萬零二百五十 (30'0250)
• 8,000,300: 八百萬零三百 (800'0300)

Note:hand signs are the same as Western hand signs. Except for six, hold out your thumb and pinky. For seven, make a "peacock head" by putting all of your fingers on your thumb. For eight, hold your thumb and second finger facing up. For nine, make your second finger look like a hook and then hold it out facing up. Source: commons:數字手勢
