When someone asks "怎么样?", how do you answer? What's the best way to answer "怎么样？“ when used as a greeting? I like this phrase a lot more than 你好 but don't know how I would answer if someone asked me 怎么样？Maybe “没什么“ would make sense?

Is this right? “睡个好觉“ and other phrases Every night before bed, I say these sentences to my son to practice my Chinese and for him to learn. We go around the room and say goodnight to his animals. "晚上好两只熊猫。睡个好觉！“ "晚上好大象。睡个好觉！” “晚上好老虎。。。” etc. I also tell him “你关灯吧“ for "turn out the light" Does everything make sense? What else can I say? He has already learned "我爱你“
