Swallows fly north

The ancient Chinese people divided the fifteen days of the Spring Equinox into three "hou's," or five-day parts. As the old saying goes, swallows fly back to the North in the firsthou; thunder cracks the sky in the secondhou; lightning occurs frequently in the third hou, which vividly reveals the climate feature during the Spring Equinox.

Egg-standing games

Standing an egg upright is a popular game across the country during the Spring Equinox. It is an old custom that dates back to 4,000 years ago. People practice this tradition to celebrate the coming of spring. It is believed that if someone can make the egg stand, he will have good luck in the future.

Some believe that the Spring Equinox is the best time to practice this game because on this day the axis of the earth is relatively balanced against the orbital plane of the earth’s rotation around the sun, which makes it easier to erect an egg.
