qī

柒（七）

You need to write the amount in uppercase on checks, for example write qī instead of 七.

All numbers in this contract are written in uppercase, including qī.

Please change the numbers on the bill to uppercase format, do not use the lowercase seven.

The bank staff reminded me to write the seven in the amount as the uppercase form.

To avoid alteration, he wrote all the numbers on the receipt in uppercase, including qī.
