This is an advertisement, which means to sell. It first appeared in the Jin Dynasty, when a formal market called Caoshi appeared in rural China. Most of them are located in traffic arteries or the location of Jindu Post Station. Because there is a lot of grass around the market, the houses are simple, mostly forage, and there are many grain and grass transactions, so there is grass everywhere. Market participants bring things to sell, so they pick up a grass and stick it in it to show their sales. In this way, the grass flag advertisement was produced. Cao Biao's advertisements were very common in ancient times, such as "Yang Zhi Selling Knives" in "The Water Margin" and "Jin Fan Selling Chicken" in "The Scholars", all of which inserted a Cao Biao into things. This form can still be seen in rural fairs.

This is the custom of ancient people. If any landlord takes a fancy to this grassland, it means that he will become the slave of this landlord, because there were many poor people at that time.

I don't know if you know, there is a minority girl who will put a feather in her head when she reaches marriageable age. If one day she is pulled out by a man, it means that she will become his wife.

So reasonable!

It is estimated that the function of the ancient straw label is the same as that of the current strip and price tag, indicating that this thing is for sale.

One special price, two parity prices and three high prices.

Inserting a straw means that there is no ridge at home, no food at home, and hunger is unbearable. Poverty is like this straw. You need to sell yourself to have a chance to live! ! !

In ancient times, when selling things, you put grass on what you sell, so when you sell yourself, you put grass on yourself, indicating that you sell yourself.

This is just a sign of retailing some goods. If there is a shop, you can hang a cover. Just because you put a straw label on it doesn't mean you are too poor to live. And those who sell straw labels are poor!

The idea of selling one's head in a straw label can be found in novels and operas. This is a folk custom.
