Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
de longue » der longue, de langue, de langues
longue do » long do, longer do
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

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: ((yang yang) OR (yang liang)) tan chia ((hui yang) OR (((pei yun) OR (lei kyun)))) de longue do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (yang liang)) tan chia ((hui yang) or (((pei yun) OR (lei kyun)))) de longue do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (yang liang)) tan chia ((hui yang) or (((pei yun) OR (lei kyun)))) de longue do ;*.
