Writing numbers with small strokes is a method of writing numbers in ancient China, which refers to the division and combination of numbers with strokes. Specifically, when a number is greater than 5, the lowercase method divides the number into two parts, the first part represents 5, and the second part represents the difference between the number and 5. For example, the number 6 is written as "six points" (five points in Chinese characters), the number 7 is written as "seven points" (five points in Chinese characters, plus two extra strokes), and so on. Of course, the writing of lowercase letters is not limited to numbers greater than 5, and numbers less than 5 also have specific writing rules.
Lowercase numbers play an important role in ancient calligraphy in China. It not only embodies the artistic pursuit of digital writing by ancient calligraphers, but also has a positive impact on the development of calligraphy in later generations. However, with the passage of time, modern calligraphy has gradually given up the tradition of writing numbers in small letters. Modern calligraphy pays more attention to the standardization and conciseness of numbers, and is usually written in Arabic numerals.
To sum up, writing numbers in lower case is an ancient digital writing method in China, which has certain artistic value and calligraphy tradition.
