Of the five sets of RMB banknotes issued by the People's Bank of China, the first three sets all use two or three different Roman numerals (I, II, III, IV, etc. ) as the crown word, and the fourth set of RMB is changed to two identical or different Chinese phonetic alphabets as the crown word, while the circulating commemorative banknotes for the 50th anniversary of the founding of the People's Republic of China only use one Chinese phonetic alphabet as the crown word.
The number is also the number of printed votes, which is the specific number in each crown word batch number. Generally, Arabic numerals are used to arrange the numbers, one for each ticket, and the numbers in the same crown number will not be duplicated. It can be seen from the number of digits of banknotes that the greater the number of votes printed by this group of crown characters, that is, the more digits, the greater the printing volume, and vice versa.

A new arrangement of crown numbers
At the beginning of 20 10, the central bank adjusted the crown number arrangement of RMB banknotes, such as "A0A000000 1" seen in the market. With the increase of cash circulation, the number arrangement of RMB banknotes will be constantly adjusted and changed (such as "A000000 1" and "A00000 1").
The fifth set of RMB 100 banknotes widely used in the market, the crown number is ten digits, the first two digits are a combination of capital pinyin letters, and the last eight digits are Arabic numerals, of which the first four digits of the crown number are red and the last six digits are black.
Relevant persons of the central bank confirmed that the combination of the crown numbers with two pinyin letters arranged each other has been used up, so the crown numbers of some RMB hundred-dollar bills are changed to pinyin letters, just like "A0A000000 1" that has appeared in the market. Moreover, with the increase of cash circulation in the future, the arrangement of crown numbers will also be adjusted.
