Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, hwang byoung
kang young » wang hyoung
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
gun hua » gui hua, tuan hua
yan jiu » pang jiu
long do » long d, long du, longer do

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) or (kang young)) gun hua wei ((((yan jiu) OR (yang jin))) or (yang jie)) long do ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang hyoung) OR (kang young)) gun hua wei ((((yan jiu) OR (yang jin))) OR (yang jie)) long do ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang hyoung) or (kang young)) gun hua wei ((((yan jiu) OR (yang jin))) or (yang jie)) long do ;*".
