Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
tan chia » tuan china, than china, can china
pei yang » wei yang, hui yang, yi yang
pei yun » lei kyun, mei yung, wei yuan
le long » de long, life long, live long
long du » long d, long do, long run
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 (yang liang)) tan chia ((du yang) OR (((pei yun) OR (pei yang)))) le long du ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (yang liang)) tan chia ((du yang) or (((pei yun) OR (pei yang)))) le long du ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (yang liang)) tan chia ((du yang) or (((pei yun) OR (pei yang)))) le long du ;*.
