sprucegoose, there are so many things that we can probably help you with locating and using, however you have given us so little to go on, so I'll ask the questions to elicit the responses that we'll need:
1. Is it a paid F or Award?
2. Presumably you are a member of a OW FF program - which one and what level are you?
3. Have you been to HKG before??
As for details about CX's The Wing Lounge (quite a deal better than The Pier, like the difference between an F and a J lounge can be), look
here. Take the virtual tour on this page for a better feeling.
As for the CX Manila lounge, definitely try it out. I've never been in it, but it couldn't be any worse than the pokey QF lounge there - see my
previous report on Manila. QF and CX lounges were, last time I was there, next to one another...
