Speaking of rapeseed, many people are confused, but it is actually the roots, plants and leaves of rapeseed flowers.

In the southern Hebei Plain, rapeseed is an important crop, and its main function is to produce seeds for oil extraction. Rapeseed oil, rapeseed leaves and roots all have a strange smell, just like coriander. Some people like it, it's terrible, and some people don't like it, it's very annoying.

The roots of rapeseed are called Brassica napus, the leaves are called Brassica japonicus leaves, and the flowers are called rapeseed flowers. Many people like the large swaths of rapeseed flowers in spring. They are fragrant and blooming with yellow flowers. In many places, they are a trump card for attracting tourists. In fact, in addition to being ornamental, rapeseed flowers are a treasure. I won't go into details here about what it contains, just a fact. During famine periods in history, people generally brought food with vegetables. If things go on like this, many people will suffer from diseases caused by malnutrition such as edema and bird blindness. But there are always some people who are thin but not bloated, which can be seen at night. People were surprised. After asking, they found out that these people often eat the whole plant of cabbage, of course, before it blooms. At that time, conditions were poor, and there was no strength or mood for research. People only knew that eating any kind of vegetable for a long time would cause swelling and starvation, but manjing would not. However, its taste keeps many people away from it, and they would rather starve to death than eat it.

Plants with comprehensive nutrition include more than just cabbage, but in southern Hebei, only cabbage has the most comprehensive nutrition. Some people say that sweet potatoes can also be used, but if they try, they will suffer from finch blindness. Carrots can cause swelling if eaten regularly, as they lack protein.

Now, people will not be so hungry that they are bloated, and manjing is also far away from the dining table. But there are always some people who can't forget this strange smell. They put some rice porridge in the pot and it tastes good to themselves, but their children won't eat it at all. There is no other way, just blanch it and make it into a dish, and the smell will fill the house. Except for the old wife, the children still looked puzzled and disgusted, and just ate the braised pork. I think, slowly, no one will plant it anymore.

When I went to the market today, I happened to see an old lady selling dried cabbage at a street stall for five yuan a pound. I went to a roll-making party and bought all of it. Don't think it's all there, once you soak it in water, it will increase in size more than ten times. Only my wife and I eat it, and I think it will last for a few months. Well, I can’t keep it to myself, I want to give some to my parents and classmates to try!

This dish does not exist in big hotels. It only belongs to people who have gone through that period of time.
