Cooking in northern China, especially in Beijing, eating "mixed vegetables" is very particular. First of all, the festive atmosphere is strong, and beginning of spring is very important. Second, to eat "stir-fry", you need to roll spring cakes to taste it.

After eating spring cakes, rolling noodles and gossiping, spring is coming. The method of side dishes is not complicated, but it is roughly like this: first, cut clean lean pork into silk about an inch long and the thickness of matchsticks, and then soak the vermicelli in warm water to make water vermicelli.
