Dr. Coal! My classmate tied it last winter, fifty. It seems a little expensive … but it's hygienic and well kept. I think it was tied in the store this year, and it didn't hurt. I just think it's not as clean as the hospital. It's not bad to stay thick and swollen for a long time, but it also has something to do with my physique. I have seen Kailuan Hospital before. It's usually okay to prick your ears. Come on!
