I want to buy liquor and go to a supermarket like RT Mart, where I sell a bunch of Wuliangye and so on. The original price was over 400 to 500, but now it's only over 100?

First, try not to go to big supermarkets when buying wine, because the bar code fee on supermarket shelves is more expensive.

Second, go to a more formal tobacco and liquor store. But be careful when buying fakes.

Third, go to the liquor chain store and expect to move directly from the eye-catching position of the store.
