Perhaps you should try some spelling variations:
chin chang » china chang, chain change, china zhang
chang kin » chang min, chang ann, chang won
keong shu » jeong su
wang dan » wang yan, wang ban, wang yidan
dan yan » dan yang, nan yan, wang yan
li chin » li chen, ii china, chi chin
yan li » yang li, yuan li, gan li

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan yan li chin chang kin ((keong shu) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan yan li chin chang kin ((keong shu) OR (cong shu)) ;*.
