What's the hurry in Pingtan Spring Festival travel rush?

On the evening of 30th, the whole family got together to eat hot pot, but the specialty of Pingtan was salty. There is also a name for eating salty food. Eating it means good luck. After dinner, everyone is waiting to watch the Spring Festival party. Or there is a saying that they can't go out on the evening of the 30th. Maybe there is a superstitious saying. Tonight, those elders will give the children lucky money. Then everyone will get up and set off firecrackers in the early morning of the 30th. Go to bed after setting off firecrackers ... get up in the morning and eat birthday noodles. Go to New Year's greetings after eating. On the first day, I will go to my elders. I will go to my friend's house to open the door on the fourth day of the next day.
