It's really infuriating, why canned bean paste can't be opened? I spent half a month trying to open it, trying it every day, and I couldn't unscrew it and put it back in place. But in the end, I still couldn't taste the delicious soybean sauce as I wanted. Now I'm so angry that I don't even have an appetite. Who is the person who designed the lid, and how much effort does it take to open it? If you don't have a strong man at home, I'm afraid you won't be able to enjoy it. What should I do if I buy it but can't eat it, and I waste it? Can I return an item? I even suspect that the lid has rusted to make it so difficult to open. I don't know if anyone else has had the same experience as me, but I'm sure it's definitely one of the most strenuous foods I've ever eaten!
