Homemade small oil

It's soybeans. Soybeans have a reputation for vegetable meat and green cows. Our Chinese medicine sees soybeans as a good temper, enhancing food digestion and promoting nutritional absorption. In addition, the soybeans are rich in osteophosphate, which increases memory. They all say that the bean curds are safe, which means that the food that we need every day on our daily table, especially when we eat all kinds of hot pots in winter, is the cheap little oil that my son likes most, and I don't know what kind of oil he buys outside, so I started to make it myself, and my son says he makes better food than he buys outside。
