Perhaps you should try some spelling variations:
yuan chang » yuan cheng, huang chang, han chang
yuan wang » yan wang, yuan kang, qian wang
long yan » long han, dong yang, long span
yan clan » das clan, yan guan, yan yuan
clan yan » nan yan
qian yan » qian jun, qian yi
chuan il » chuan fa, chun i

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: long yan clan yan ((((yuan wang) OR (yuan chang))) OR (qian yan)) chen chuan il ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long yan clan yan ((((yuan wang) OR (yuan chang))) or (qian yan)) chen chuan il ;~".
• Adding a wildcard symbol may retrieve word variants: long yan clan yan ((((yuan wang) OR (yuan chang))) or (qian yan)) chen chuan il ;*.
