The number is capitalized as one and written as one; Two words are two; Three is written as three; Four magic weapons for writing for the boss; The five major works are five; The Sixth National Congress was written as Lu; Seven are written together; Eight is written as eight; Nine is written as nine; The top ten says pick up. So 18 170 yuan sixty-eight cents is right.
Chinese amount in words should be marked with the word RMB, and amount in words should be filled in immediately after the word RMB, without leaving blank.
