After World War II, the Korean Peninsula was bounded by the 38th parallel, and the United States and the Soviet Union were in charge of each side. Later, with the support of the United States and the Soviet Union, the South established the Republic of Korea and the North established the Democratic Republic of Korea. At that time, the land reform was carried out in the north, and the people were assigned to the fields, and their lives were quite moist. There is no land reform in the south, and the people live a bitter gourd life. Yanbian, Jilin belongs to Korean culture and is called "Little Korea". The hot pot there is called "Army Hot Pot". This kind of hot pot is a bit like a warm pot in Jianghuai area. Many ingredients, meat and vegetables are put in pots and cooked on the stove. It's just that the hot pot in the army has less ingredients and is not as rich as the warm pot in the Jianghuai area.
You can say that this thing is leftovers, or you can say that it was picked up from the sewage bucket. A few years ago, a classmate traveled to Korea and really asked Koreans about it. Older people generally don't say this, and young people know its origin, but Koreans "have a little self-esteem." Of course, they don't want to talk about the matter of picking up food from sewage barrels to satisfy their hunger because of the hardships of life.
Team hot pot is not made of leftovers, but swill thrown in the garbage by the US military. At that time, Koreans were particularly poor, so they went to the US military station to pick up food from the garbage dump, put all kinds of food in a pot, and ate it with some water! Team hotpot is a kind of hotpot invented by Koreans in 1950s. At first, the ingredients of the hot pot came from the food discarded by the US military in the trash can, such as some ham, lunch meat, canned meat and so on. This is swill food, not leftovers.
