What do you mean when Taobao said it was out of stock, so it was cheap?

That is, his goods will not be produced any more, and they have broken down. For example, there used to be five yards, but now there are only two or three yards left. Broken code is out of stock, which means it won't happen again in the future. Now the seller just wants to sell what he has and clear the warehouse. So it's cheaper to sell.
