Dear Uncle Wang,
Hello!My dear Uncle wang,I want to tell you something.I've got a problem recently.The problem is something about you.You returned home very late these days.Yes,it's maybe not my business,but you then turned on the TV,and turned up the volume.I couldn't sleep because of that.I haven't had a good sleep for several days.Could you please turn down the TV in the following days?I'll appreciate that.
Great thankful!
