Perhaps you should try some spelling variations:
china zhang » china chang, cheng zhang, chin chang
zhang wang » zhang fang, zhang zhang, zhang fan
hyoung gun » young eun
yang jie » yang jin, yang di, yang jui
yang jun » yang jui, pang jun, yang jin
yan je » han je
fang » lang, gang, fan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: fang sheng ((((yan je) OR (yang jie))) OR (yang jun)) china zhang wang hyoung gun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "fang sheng ((((yan je) OR (yang jie))) or (yang jun)) china zhang wang hyoung gun ;~".
• Adding a wildcard symbol may retrieve word variants: fang sheng ((((yan je) OR (yang jie))) or (yang jun)) china zhang wang hyoung gun ;*.
