Pigs are usually slaughtered in the early hours of the morning, shortly before dawn, mainly to ensure that the meat is fresh so that pork can be sold the next morning. It takes about 4-6 hours from slaughter and cutting to transportation and wholesale to store retail, and the first batch of people visiting the morning market arrive at the market at 5 o'clock.
You need to choose a date to kill a pig:
You need to choose a good day to kill pigs. The twelfth lunar month is the busiest month of the year. There are not only many marriages, but also many kinds of banquets. Generally, you have to stagger with many social parties, and you can't choose the date of going to sea. You can't kill pigs for four days, and you can't kill pigs if there are elders and children at home for their birthdays.
In short, the day of killing pigs, under normal circumstances, is a good day to ask the elders who know how to kill pigs.
