I suggest FANG. It is edgy!

names are very special, and the thing about an english name is that you are going to encounter a lot of other people with the same name (which can be annoying) going by sound: fenny, fenessa (personalized spelling of 'vanessa') going by meaning/homophone: maple, phoenix (that's unique, too)

Fey, can be spelt Faye. ^^ Or Fern. Fergy/Fergie.

Fawn would be the closest in pronunciation to "Feng". Renae has no relation to Feng, but is a good name.

NI hao ma feng , You want it to sound like "feng" or to have the same meaning ? If you want a name that sounds like feng here you go : Fay ,fawn,fawna,Ferryn, but most of them are not really commonly used these days . You could check the following list of names unrelated to your name also ,maybe you could pick a nice one : http://www.babynamesfamily.com/nationality/english_girls_names_29.html 88 :)
