Spring Equinox: A科普 Video Exploring Spring Changes and Customs

What is the Spring Equinox?

The Spring Equinox, also known as the Vernal Equinox, is one of the four most important solar terms in traditional Chinese culture. It marks the beginning of spring and is celebrated on March 20 or 21 each year. During this time, the sun is directly above the equator, resulting in nearly equal day and night lengths all over the world.

Natural Changes in Spring

Temperature Rises

As the Spring Equinox approaches, the temperature gradually rises. This is a sign that winter is over, and the warm season is about to begin. Flowers start to bloom, and trees begin to leaf out.

Lengthening Days

One of the most noticeable changes during the Spring Equinox is the lengthening of days. As the sun’s position in the sky moves northward, the days become longer and the nights shorter.

Animals Awakening

Animals that have been hibernating during the winter start to awaken. Birds return from their wintering grounds, and insects become more active.

Customs and Celebrations

Dragon Boat Festival

While not directly related to the Spring Equinox, the Dragon Boat Festival is a traditional Chinese festival that takes place around the same time. It commemorates the poet Qu Yuan, who drowned himself in the Miluo River in the 5th century BC. People celebrate by racing dragon boats and eating zongzi, a sticky rice dumpling.

Eating Eggs

In some regions, people have the custom of eating eggs on the Spring Equinox. Eggs are believed to symbolize life and fertility, and eating them is thought to bring good luck.

Planting Trees

The Spring Equinox is also a good time for planting trees. It is believed that planting during this period will ensure strong growth and a good harvest.

Conclusion

The Spring Equinox is a time of renewal and rebirth. It symbolizes the beginning of spring and the awakening of nature. By understanding the natural changes and customs associated with this time, we can appreciate the beauty and significance of the Spring Equinox.
