Perhaps you should try some spelling variations:
yan guan » gan guan, yan yuan, yang guang
tan chia » tuan china, than china, can china
hui ying » huei ying, hui ping, hui yang
hoi ying » li ying
lei kyun » lee kyung, lee kyu, pei yun
wan yan » wang yan, nan yan, wai yan
de long » le long, de longue

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wan yan) or (yan guan)) tan chia ((((hui ying) OR (hoi ying))) or (lei kyun)) de long run ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yan) OR (yan guan)) tan chia ((((hui ying) OR (hoi ying))) OR (lei kyun)) de long run ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yan) or (yan guan)) tan chia ((((hui ying) OR (hoi ying))) or (lei kyun)) de long run ;".
• Adding a wildcard symbol may retrieve word variants: ((wan yan) or (yan guan)) tan chia ((((hui ying) OR (hoi ying))) or (lei kyun)) de long run ;*.
