1, the mall is renovated or closed, and the inventory is cleared.
2, clothing broken code
3, the old style can not be sold at the regular price, and the backlog warehouse is discounted and cleared.
That's usually all. For example, many famous brands are discounted, which may be old models, or foreign goods cannot be sold, and they can still sell at a good price when they are transferred to Asia.
It is estimated that there are also cold brands of clothes sold in the name of sale. Sometimes you will find that there are many brands of clothes that you have never seen before in the special sale area of the shopping mall. Even after the discount, the price is similar to that of ordinary brands, but the style and workmanship are really average. You'd better buy less of this kind of clothes.
The above is all my experience, please refer to it.
