In fact, sweet potatoes can be said to be relatives of sweet potatoes, and they also grow in the ground. When they are dug up, they are covered in mud, and the size is similar to that of sweet potatoes. The big size will never be mistaken for potatoes. But the shape of sweet potato is absolutely different from that of sweet potato. Sweet potato is a spindle with a round top, not a long strip like sweet potato. The taste of sweet potato is completely different from that of sweet potato. It is more like a kind of fruit, very tender, white pulp, seedless and seedless, sweet in taste, without any sour taste, with a little earthy aroma, which can be said to give people a very pure feeling. The skin of sweet potato is not cut with a knife, but torn by hand, just like the feeling of tearing tender bark. Of course, the skin of sweet potato is much thinner than the bark, and it is also very tough. After it is torn off, it will show very smooth white meat, and its shape will not change at all.
Two days ago, I looked up sweet potato on Baidu Encyclopedia on a whim, and found that the explanation was that sweet potato was an alias of sweet potato, or that sweet potato was a proper name, and sweet potato was an alias of sweet potato, but the real sweet potato was not mentioned at all. Although there are different customs in different places, since sweet potato already has its own name, it is too unkind to occupy a sweet potato as an alias.
