Hung is such a sweet guy so I feel bad saying this, but there is a bit of difficulty created by his accent and I usually have no trouble understanding accents (I do have an auditory processing disorder but it's never been this hard for me before). That being said, he is so kind and willing to help and always enthusiastic. My only critique is that he got fairly behind in the material by the end and had to breeze through quite a bit on the last day. As a whole, I would still recommend taking him, especially if he teaches with Khankan again. I would DEFINITELY take him over Pires or Kane.
