Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yang mind » yang cindy, yang jin, tang min
sang minh » kang minah, anh minh, song min
chai tan » chai tam, chai onn
hong hai » shang hai, zhong tai, dang hai
yong ka » ong ka, yang ka, yong kim
ka chai » ka chuan, kim chai

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: wang yong ka chai tan ((yang mind) OR (sang minh)) ((hong hai) OR (hong tan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ka chai tan ((yang mind) OR (sang minh)) ((hong hai) or (hong tan)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ka chai tan ((yang mind) OR (sang minh)) ((hong hai) or (hong tan)) ;*.
