Hi E-Speller friends!Surprisingly, my douyin video about 头皮屑，眼屎，耳屎 got popular. I didn't know people prefer funny videos to serious teaching ones. Anyway, did you get the answer for the question at the end of the video? Don't tell me it's "nose shit", haha!太奇怪了，这个讲“头皮屑，眼屎，耳屎”的视频在抖音竟然有点儿火! 早知道这样，我辛苦录那么多正经的教学干嘛。Anyway，视频最后的问题你们回答出来了吗？千万别告诉你是“(╬▔皿▔)凸”，哈哈！Let's talk about this topic more!不管怎么说，我还是趁机多讲一点儿！Dandruff is dandruff. There's nothing funny to say about it. Just remember it.I think I might have dandruff.Can I buy some dandruff shampoo?Is that dandruff on your shirt or snow?“头屑”就是“头屑”，没啥好说的，记住就好！（三个例句 ………………………………
