Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
tonga eiu » kong eiu
lang yan » wang yan, wang yang, zhang yan
kang min » kan min, tang min, kang minah
hong shu » cong shu, tong shui, wong shiu
yang li » yang lin, yang di, yang xi
xu kang » wu kang, xi kang, xu gang

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang yan ((((yang liang) OR (yang yang))) or (yang li)) xu kang min ((hong shu) or (tonga eiu)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((((yang liang) OR (yang yang))) OR (yang li)) xu kang min ((hong shu) OR (tonga eiu)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((((yang liang) OR (yang yang))) or (yang li)) xu kang min ((hong shu) or (tonga eiu)) ;*".
