What does the calendar taboo mean?

Due to the working people's mastery of weather, climate, natural phenomena and the rhythm of biological activities since ancient times, our ancestors gained some experience through long-term observation and practice, and today's yellow calendar (that is, the taboos on the calendar) came into being.

Appropriate is appropriate, what can be done today. Avoid, it is forbidden to do something today.

Generally, most rural areas in China have such social activities. Many farmers will go out to trade according to the date in the solar calendar, and ordinary people are willing to go to the market and buy what they need according to the date in the solar calendar.
