Perhaps you should try some spelling variations:
chen kyoung » chen yong
wang liang » wang yang
huang jing » huang ting, huang ying, wang jing
kyoung yun » young yun, kyoung yang, hyoung gun
young hr » young er, young _, young 5
yu chen » yu cheng, yi chen, yulu chen
young 4 » young _, young 5, young 6

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: dong ((wang liang) OR (huang jing)) yu chen kyoung yun ((young hr) OR (young 4)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((wang liang) or (huang jing)) yu chen kyoung yun ((young hr) OR (young 4)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((wang liang) or (huang jing)) yu chen kyoung yun ((young hr) OR (young 4)) ;*.
