Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung yang » kyoung yang
hong hai » shang hai, zhong tai, dang hai
yang si » yang di, yang xi, yang yi
yan jiu » yang jie, yang jin, pang jiu
hong ng » hong jong, hong hong
kong » long, pong, ong

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang hyoung yang si (ren or rein) yan jiu ((hong hai) or (((hong ng) OR (hong kong)))) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung yang si (ren OR rein) yan jiu ((hong hai) OR (((hong ng) OR (hong kong)))) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung yang si (ren or rein) yan jiu ((hong hai) or (((hong ng) OR (hong kong)))) ;".
• Adding a wildcard symbol may retrieve word variants: lang hyoung yang si (ren or rein) yan jiu ((hong hai) or (((hong ng) OR (hong kong)))) ;*.
