Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung yang » kyoung yang
shang hai » shang kai, dang hai, chang ha
hong hai » zhong tai, dang hai, hong tan
yang si » yang di, yang xi, yang yi
yan jiu » yang jie, yang jin, pang jiu
hong ng » hong kong, hong jong, hong hong
ren » rent, rene, rein

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 yan jiu ((((hong hai) OR (shang hai))) or (hong ng)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung yang si ren yan jiu ((((hong hai) OR (shang hai))) OR (hong ng)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung yang si ren yan jiu ((((hong hai) OR (shang hai))) or (hong ng)) ;*".
