Perhaps you should try some spelling variations:
wang shiyong » wang hyoung
wang lihong » wang liang
yong jing » yang jing, gyeong jing, xiong jing
tan yong » tan hong, tan kong, tan yang
eang hay » kang han
yan tan » tan tan, yan clan, yan guan
hai » hadi, haji, hari

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 lihong) OR (wang shiyong)) wang yan tan yong jing ((eang hay) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang lihong) OR (wang shiyong)) wang yan tan yong jing ((eang hay) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang lihong) OR (wang shiyong)) wang yan tan yong jing ((eang hay) or (dang hai)) ;*.
