Perhaps you should try some spelling variations:
yan guan » yang guang, yihan guan, quan guan
yan yuan » fang yuan, nan yan, yan clan
gan guan » quan guan, fan guon, gui guan
hua chen » jui chen, yu chen, a chen
chen yan » chen yang, chen tan, chen yun
shi rong » yi rong
rong sau » rong su, wong sau, kong sar
yan shi » yan zhi, yun shik

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: (wan OR lang) ((((yan guan) OR (yan yuan))) OR (gan guan)) hua chen yan shi rong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) ((((yan guan) OR (yan yuan))) or (gan guan)) hua chen yan shi rong sau ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or lang) ((((yan guan) OR (yan yuan))) or (gan guan)) hua chen yan shi rong sau ;*.
