In the Northern Hemisphere, the Spring Equinox （Chinese: 春分 chūn fēn）occurs when the sun crosses the equator line, heading north. This event marks the start of the spring season in the northern half of the globe. The arival of the Spring Equinox marks that the spring has passed halfway through. The singing birds and the blooming flowers make up a wondrous scenery in spring. In 2022, the Spring Equinox starts from 20th March and ends on 4th April.

Swallows Fly North
The ancient Chinese people divided the fifteen days of the Spring Equinox into three "hou's,"(Chinses:候) or five-day parts. As the old saying goes, swallows fly back to the North in the first hou; thunder cracks the sky in the second hou; lightning occurs frequently in the third hou, which vividly reveals the climate feature during the Spring Equinox.
Reward Farm Cattle
This practice is popular in the southern area of the lower reaches of the Yangtze River. As the Spring Equinox comes, farm work starts and both the farmers and the cattle start to become busy. Farmers will reward cattle with sticky rice balls to express their gratefulness. Meanwhile, people will also make sacrifice to birds, to thank them for bringing signals for farm work and to ask them not to eat grains later in the year.
