Beef 1.5 kg, celery 2 kg, pork 1.5 kg, scallion 1 kg (I suggest you use Chinese cabbage, which consumes too much meat, so does Chinese cabbage), mutton 1.5 kg, carrot 2 kg, as for meat, pork/kloc. God, when are you going to pack? You poor children, it depends on how big jiaozi you are going to pack. Put less stuffing. Hehe, good luck. Here, those vegetarian dishes are enough for you to cut for a while. Fortunately, you can go to the vegetable market to buy meat.

500,25 people, one person is 20, I hope they are full.

I have calculated the cost for you. Excluding dumpling wrapper 120 yuan. It depends on what kind of meat you buy, not too thin, just a little fat. It is delicious.
