The first one is what we know as lettuce. I believe everyone has done it at home. Then when we eat mala Tang, many people will take some lettuce or baby dishes to match it. The stems of these vegetables are very big and heavy, accounting for a very large proportion. When we buy it in the supermarket, it is only a few dollars, and when the merchant wholesales it may be a few cents, but when we eat it in the mala Tang shop, it is only a few dollars, and it is very small.
The second is the potato we know. I believe everyone knows the price of potatoes in our supermarket, which is very common in our daily life. These potatoes are cut into small pieces at the merchant's side and soaked in water, so that their value is worth one or two pieces in the store. Potatoes will melt and break easily when cooked at high temperature, and you will find that you can't see anything in his bowl, so you can't choose one thing.
The third kind is a common thing in our daily life, that is, tofu. A piece of tofu we buy every day costs only a few cents, and tofu itself contains a lot of water. I believe you all know that its weight is the same as the potato in the second article. Easy to disperse at high temperature. We often only see a bowl of tofu after ordering, but we can't eat the whole piece of tofu. Therefore, when we go to eat spicy food, we'd better not order these things.
