At 11:58 a.m. (Beijing Time) on February 4th, people across China will mark Lichun (立春）or the Beginning of Spring.
The traditional Chinese lunar calendar divides a year into 24 solar terms, with Lichun being the first term. It refers to the day when the sun is at the celestial longitude of 315°.
The day is usually marked with certain specific traditions:
Biting the spring:
Chinese people eat spring rolls to observe the custom of “biting the spring”. Spring rolls refer to a thin sheet of rolled, stuffed, fried dough, with vegetables and meat inside. In some parts of China, people eat noodles and dumplings instead.
It’s believed that if someone can make an egg “stand up” on this day, he or she will have good luck throughout the year. If you are planning on giving this a try, it’s advisable to choose eggs that are 4 or 5 days old, as the yolk tends to sink down in them, making it more likely that they’d “stand up.”
Artworks on the door:
People usually decorate the entrance to their homes with cut-outs of Chinese calligraphy or paintings.
A spring outgoing:
Generally, families and friends tend to get together on the day for a picnic or some fun outdoor activities.
