Why does everyone say that the winter solstice is buried? Any allusions?

The allusion is that the ancients thought that after the winter solstice, the days became longer and longer, the shortest days and the longest nights, symbolizing the alternation of Yin and Yang.

In the Tang and Song Dynasties, the solstice in winter was the day of ancestor worship. On this day, the emperor went to the suburbs to hold a ceremony to worship heaven. On this day, people must pay homage to their dead parents. There are still some places to celebrate the winter solstice.

Refers to the people in the past, with the backward migration of time, as long as they have been to this world, they will become ancients. The only difference lies in the period or era.

The ancients are a very ancient race, and their historical estimates need hundreds of millions of years to calculate, and the planet where they originally originated is no longer testable. They explored the universe in a huge flying city.

There may be more than one flying city like Atlantis, and it has changed for many generations. The ancients first mastered the wormhole technology and established the stargate.

In order to find the meaning of life and create a perfect life form, the ancients kept sowing the seeds of life on the planet with suitable conditions, transforming the environment and letting it evolve and develop, while the ancients watched and studied.
