Eight is the capital form of the number eight. It is often used to indicate eight in bookkeeping. The original meaning of the word "rake" refers to a toothless rake for collecting grain. The rake is shaped like the number 8 and is used to represent the number 8. In modern Chinese characters, Ba is no longer used as the capital form of the number eight, but is replaced by Ba itself. When filling out a check or invoice, you can see that the word "Ba" is the capital form of the number 8.
