This friend, I don't know if you are a caring person, but I can say that I am a caring person. I have worn this underwear you mentioned, and there is a big gap between the quality, fabric and comfort of other kinds of underwear in the supermarket. It has many functions beneficial to human body. Every caring person can never say that underwear can cure all diseases. It is a kind of physical therapy and health care underwear. I generally choose to block those who are completely ignorant of the actual situation and full of nonsense. I suggest you try it, just a pack of cigarettes and a game of mahjong. Perhaps, what you get is very comfortable and beneficial to your health. what do you think? Even if it is cheating, will it only lie to you? Ha ha.
