The first and most important thing is to worship ancestors. Every family will prepare fruit and other sacrifices to worship their ancestors. The second thing is to "bite the spring" when it begins. In fact, it is to eat some fresh food (this kind of food varies from place to place), feel the breath of spring and prevent from falling asleep. The third thing is to go for a spring outing. After beginning of spring, people like to go out for a spring outing in spring, which is also the main form of spring outing.
Beginning of spring is not only the first of the 24 solar terms, but also an important festival. Astronomically speaking, it marks the beginning of spring.
