"Spring Equinox” arrives around March 21 every year and on this day, the sun is vertically above a point on the equator.

“Spring Equinox” indicates two meanings.Firstly, on this day, the night and day are approximately equally long with 12 hours each. Secondly, it’s the mid-point for the spring season.

After this day, the sun continues to move to the north hemisphere and the temperature continues to rise. Daily average temperature in most areas in China reaches 0 degree Celsius above.

During the Spring Equinox, an old traditional practiced by Beijing locals is offering sacrifices to the Sun god.
