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

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 jin ((ran ying) OR (tan yang)) ((ii eang) OR (((yi chang) OR (ii chang)))) hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung yang jin ((ran ying) or (tan yang)) ((ii eang) or (((yi chang) OR (ii chang)))) hay ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung yang jin ((ran ying) or (tan yang)) ((ii eang) or (((yi chang) OR (ii chang)))) hay ;*.
