What is the principle of pressing the palace of life every birthday? Which expert can explain it to me?

When the sun rises, it is the first to rise. The ancients believed that the sun was the guarantee of life, and not a trace of the sun died. Therefore, it is the beginning of life to use the hall to mark people coming out of the mother's womb and seeing the sun. And this sunshine actually refers to the sunrise time of the constellation. Latitude and longitude vary from place to place, and so do seasons. Living in peace is just a general rule, because generally speaking, the sun rises at dawn. In some areas, the solstice is the sunrise in Yin Shi 15 days after summer; Sunrise occurs from winter to dawn fifteen days later.
