The superstitious color of the old imperial calendar

In ancient times, the contents of the old imperial calendar were divided according to the calendar arrangement of months, days and solar terms, and most of them focused on specific guidance on farming, workers' life, and the choice of auspicious days. However, due to the needs of feudal rule, the contents of the old imperial calendar have also been painted with strong superstitious colors, such as choosing "auspicious days in the zodiac" and fortune-telling by looking at faces, which has become a vivid historical portrayal. Current affairs, politics, economic life, science and technology, military affairs, astronomy and geography, culture and art, Spring Festival couplets proverbs and so on, which are closely related to the special historical era, have become the source of the collection value. The calendar recorded in the Imperial Calendar is generally limited to one year, and it changes in the second year. It would be wrong to look at this year's calendar with last year's "imperial calendar". So people often use the "old imperial calendar" to describe those conservative and outdated ideologies.
