Pig-killing dishes originated in the northeast countryside. After the autumn harvest every year, people will slaughter their fat pigs to celebrate the harvest, or cook various dishes to entertain their neighbors before the Chinese New Year. This is the place where pigs were killed in the northeast. Liaoning people especially like to eat pig-killing dishes. "Kill pigs" is usually after Laba, so there is a folk proverb "Don't cry, son, kill pigs after Laba".
