Why did beginning of winter kill pigs?

Pigs must be slaughtered from winter to the future and before the start of spring, because it is easy to get worms when pork is preserved in the coming year, so every household must kill pigs before the start of spring.

Generally speaking, every family starts to kill pigs after beginning of winter every year. On the day of killing pigs, the host invited three or five friends or neighbors to get together to eat pigs. This activity will be held at the end of each year. Generally, every household in the village takes turns to treat guests. In fact, it is a grand family activity, which aims to bring the neighborhood closer and increase the atmosphere of the New Year.

When the Chinese New Year approaches, according to the rural custom, people will kill their own pigs and then invite relatives and friends to have dinner at home. The main content of the dishes is pork, such as fried pork liver, boiled pork, braised pork and so on.

We call this kind of party "eating pork soup". After that, we will smoke bacon, fill sausages, burn pig's trotters and so on to prepare for the Chinese New Year. In order to prevent rot, people will hang it in a ventilated place until it is finished.
