Perhaps you should try some spelling variations:
wang dong » wang yong, wang hong, wang jing
wang yang » wang yan, wang liang, wang yanling
hoang hai » hong hai, dang hai, shang hai
rest yan » ren yan
hoang h » hoang _, hoang vu, hoang sy
won sau » wong sau, wong sam, wong siu
yan ji » yan jiu, ban ji, pan ji

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang dong) or (wang yang)) ((hoang hai) OR (hoang h)) rest yan ji won sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang dong) OR (wang yang)) ((hoang hai) OR (hoang h)) rest yan ji won sau ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dong) or (wang yang)) ((hoang hai) OR (hoang h)) rest yan ji won sau ;".
• Adding a wildcard symbol may retrieve word variants: ((wang dong) or (wang yang)) ((hoang hai) OR (hoang h)) rest yan ji won sau ;*.
