What are the nine traditional digital cultures in China?

China: 1. The number "nine" is closely related to ancient myths and legends. Originally written in the dragon totem culture, it later evolved into the meaning of "sacred" and "auspicious", and later it was widely borrowed. The Book of Changes divides one to ten into odd and even numbers. According to the ancient theory of Yin and Yang in China, odd numbers are Yang and even numbers are Yin. Odd numbers symbolize heaven, masculinity, even numbers symbolize earth and femininity. 2. Because nine is the largest single digit, it is regarded as an imaginary number and an extreme number to the sun in China, which often means the most and countless meanings, such as: Nine Days/Nine Days Clouds/Nine Days White Clouds (to describe the sky is very high), Nine Dishes (to describe Panshan Road), Nine Quiet (to describe extremely secluded and deep places), Nine Niu Yi hairs, Nine Nine narrow escapes, Nine.

In addition, nine is homophonic with the Chinese character "Jiu", so nine is regarded as a number representing dragon.

Japan: In Japan, the number 9 is taboo (because its pronunciation is similar to "bitter").
