After a long time by Amway, I finally pulled the weeds 💠Sense of use: The thread should be soaked for a little longer, so that the liquid is close to the green part, otherwise it will start to hurt (maybe 耳洞 is relatively small) But I found that it may not be used, because 耳洞 has been in good condition, probably 耳洞 is laser shot (like roast pork, it burns the meat 😭, but the advantage is not so much) 🌀 The overall feeling is that this is okay, you can play it when you are bored, it is simply winning the world
