Is gutter oil usually sold in malls or supermarkets? I don't know what kind of gutter oil is, I'm afraid to buy gutter oil, usually gold dragon fish brand cooking oil...

Go to a regular supermarket and you won't get gutter oil. The channels of purchase are also relatively regular

You can also go to various cooking oil dealers and the price is much lower

Tianjin, you can go to Tianjin Lipeng to see if you think it's okay. I think it's loaded in the COFCO factory and the quality is more secure

It's a good idea to go to a supermarket or a supermarket to get gutter oil.
