Questions with V不V
V + 不 + V (+ Obj.)？
Instead of adding 吗, you can ask a yes/no question by saying the verb both ways — positive then negative: 你去不去？ literally "you go not go?" = "Are you going?" It works with adjectives too: 好不好？"Is it good?" The answer just picks a side: 去 or 不去.
Short tags like 是不是, 对不对, and 好不好 hang on the end of a statement to ask "right?" or "okay?": 我们去公园，好不好？ One rule: this pattern IS the question, so never add 吗 on top.
