Perhaps you should try some spelling variations:
wang yidan » wang yan
dang haji » dang hai, dato haji
hoang ya » hoang vu, hoang _, hoang h
hoang sy » hoang vu
hua wang » hwa wang, hua jiang, yuan wang
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((hoang ya) or (hoang sy)) hua wang yidan tin ((((hong ghi) OR (hong hai))) or (dang haji)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((hoang ya) OR (hoang sy)) hua wang yidan tin ((((hong ghi) OR (hong hai))) OR (dang haji)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((hoang ya) or (hoang sy)) hua wang yidan tin ((((hong ghi) OR (hong hai))) or (dang haji)) ;*".
