Arowana peanut oil is ok, and the quality of products produced by big factories is also ok, as long as what you buy is not fake. In fact, the profit of peanut oil is still very good. I think the peanut oil squeezed by our own oil mill here is only 10 yuan a catty, and the cheapest time is less than 10 yuan. So the oil in the supermarket is basically ok, so the expensive price should not be fake.
