Classification of signatures in string stores

There are two kinds of signatures inserted on strings, one is wood and the other is iron.

A string of hot pot is signed by two people. Two signers mean that this thing is more expensive than the signer. It costs 50 cents for a person to sign. Both represent this thing. Just have two signatures.

A bunch of household things we ate were labeled, one with a signature and two signatures. Two signatures were more expensive than a dish, which made people kneel down.

Some goods can have four or five labels. Because each label costs a lot, the more expensive the product is, the more labels it will wear. So you can look at the more expensive products and wear more labels when choosing goods, but there is nothing to say. After all, the cost is there.
