Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung yang » kyoung yang
yang jun » yang jui, pang jun, yang jin
ran ying » fan ying, tan ying, jin ying
tan yang » dan yang, tan ying, tan yong
ii chang » vii chang, ii changes, iii change
yi chang » ying chang, jin chang, vii chang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung yang jun ((ran ying) OR (tan yang)) ((ii chang) OR (yi chang)) hay ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung yang jun ((ran ying) or (tan yang)) ((ii chang) or (yi chang)) hay ;*.
