Hahaha- beyond the initial disputes including the cheeky numbered pinyin I don't know why you have both bothered. It's a bit like if I were a HGV fitter (much knowledge needed, equal to a GP they say and I can believe it) arguing with a DIY mechanic who can change sparking plugs; having the impudence to argue with me about fifth-wheel-tractor-trailors and the like. You do have to admire him in a way, every time one of you knocks him through the ropes, his corner sloshes him down with water and he clambers right back again.
