Mr. Yan
In the raws, Xiang Huai first asks if Xue Xi knows what word is formed when one word is removed from “老公公”,with “老”meaning old while “公公”means either grandpa or father-in-law. To which Xue Xi replies “公公”. I assume Xiang Huai wanted Xue Xi to answer “老公” instead which means husband. For the amusement park question, Xiang Huai wanted the answer “木马” which sounds similar to ”muma”. ”Muma” was stated in the raws. Not sure what it means though, maybe 妈妈 which means mother.
