Why are some people used to celebrating the Lunar Birthday?

The ID card is full of Chinese birthdays. Later, when astrology prevailed, I thought I was Capricorn, and later I realized that I was Aquarius. The reason should be the living environment. If you are in the countryside, there will be more Chinese birthdays. Although farmland is no longer the main source of income for my family, it is natural (perhaps exaggerated) to record important days in the lunar calendar. My grandfather uses the lunar calendar to record my father's birthday, and my father also uses the lunar calendar to record my birthday. After all, farming by the solar calendar is still not so reliable, and the solar calendar is not so long in the countryside. When we are at home, if we say the date, it is usually what day it is today, and we never say the date.
