tang yun » yang yun, chang yun, fang yuan
yang lin » yang jin, wang lin, yang li
lin ling » liu ling, ling liong, lin meng
ling hai » dang hai, ling li, hong hai

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: ((lang yan) OR (zhang yan)) ((tang yun) OR (long run)) gain yang lin ling hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (zhang yan)) ((tang yun) or (long run)) gain yang lin ling hai ;".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (zhang yan)) ((tang yun) or (long run)) gain yang lin ling hai ;*.
