Perhaps you should try some spelling variations:
yong xiang » gong qiang, yang liang, yong phang
wang yong » wang yang, wang hyoung, wang yan
xiang wei » liang wei, zhang wei, wang wei
zeng doug » zeng douglas
jeng dong » eng hong
thing » think, thin
things » thinks, thins
sin » sign, sind, skin

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 xiang wei ((last thing) OR (last (thing OR things))) ((zeng doug) OR (jeng dong)) sin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong xiang wei ((last thing) or (last (thing or things))) ((zeng doug) OR (jeng dong)) sin ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong xiang wei ((last thing) or (last (thing or things))) ((zeng doug) OR (jeng dong)) sin ;*.
