What is the nine characters of birth?

The ancients used branches to measure time, and took a word from the combination of heavenly stems and earthly branches to represent a time unit. For example, last year was Shen Jianian, and this year is Yi You Year. The same is true of the month, day and time. In this way, each time unit is represented by two words, while a person's birthday is represented by four time units: year, month, day and hour, so there are eight words in total. Because heavenly stems and earthly branches can also be used to indicate the direction and orientation, contrary to the five elements, and there are 12 zodiac signs to match it, so birthdays can be used for fortune telling. For example: Chen Jia, Chen Bing, Xu Chen, Chen Geng, Ren Chen, Jia Yin, Chen Bing, Xu Yin, Geng Yin and Ren Yin.

This 10 day is Dragon and Tiger Day, which is very auspicious. Personally, I feel that China's birthday is more delicate and complicated than the western 12 constellation, so now more people know their own horoscope than their birthdays. However, this is all superstition, and there is nothing to do with leisure.
