How many ways to write "one" in ancient times?

Arabic numerals: 1, 2, 3, 4, 5, 6, 7, 8, 9, 1000, 1000 Chinese: one, two, three, four, five. Whether it is Arabic numerals (1, 2,3 ...) or so-called Chinese lowercase numerals (1, 2,3 ...), because the strokes are simple and easy to be altered and tampered with, the numbers on general documents and commercial financial bills should be capitalized in chinese numerals: one, two, three, four, five, six, seven. These Chinese characters have existed for a long time, and they are used as capital figures and belong to borrowing. The complicated writing of this number was fully used as early as the Tang Dynasty, and then it was gradually standardized as a set of "uppercase numbers".
