Perhaps you should try some spelling variations:
yan yuan » fang yuan, nan yan, yan clan
yan guan » gan guan, yang guang, yihan guan
juan tan » huan t'an, juan rana, juan a
tan jing » tan ying, wang jing, bian jing
kang sar » kong sar, kang tae, kang ca
yan san » yan clan, yan wang
jing ji » ying jin
ji kang » jin kang, xi kang

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: nan ((((yan san) OR (yan guan))) OR (yan yuan)) juan tan jing ji kang sar ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((((yan san) OR (yan guan))) or (yan yuan)) juan tan jing ji kang sar ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((((yan san) OR (yan guan))) or (yan yuan)) juan tan jing ji kang sar ;*.
