Yao Qian is a big liar. I was cheated by her. She sold us products ranging from 10 to 20 at a high price, and Taobao had them all. A manufacturer has more than 20 brands, and she wants more than 100, apple vinegar compressed tablets, bitter gourd compressed tablets, and foot-sticking and dampness-removing stickers. Very cheap products are useless to lose weight. The more you eat, the fatter you get, which makes the density inside your body unbalanced. Don't trust her.
