Some of my classmates lose weight by drinking Pu 'er tea and oolong tea. After lunch and dinner every day, the students who drank oolong tea lost 8.5 Jin in two weeks, and the students who drank Pu 'er tea lost 6 Jin in two weeks. Some of them are sold in supermarkets, and they bought leisure scales, saying that they can drink for two weeks for ten dollars. I sincerely tell you the effective methods I know and hope to adopt my answer. Thank you.
