Perhaps you should try some spelling variations:
yan guan » gan guan, yan yuan, yang guang
tan chia » tuan china, than china, can china
hui yang » hui ying, du yang, h yang
lei kyun » lee kyung, lee kyu
pei yun » mei yung, pei yang, wei yuan
le long » de long, life long, live long
wang » wing, wan, lang

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: ((wang yan) OR (yan guan)) tan chia ((hui yang) OR (((lei kyun) OR (pei yun)))) le long run ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yan guan)) tan chia ((hui yang) or (((lei kyun) OR (pei yun)))) le long run ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yan guan)) tan chia ((hui yang) or (((lei kyun) OR (pei yun)))) le long run ;*.
