shang kai » shang hai
lang yan » wang yan, zhang yan, yang yang
ying hua » ming hua, wang hua, ying zhu
hong hai » shang hai, zhong tai, dang hai
hua tan » hua ban, huan t'an
tan xin » fan xing, tan sinh, tan ying

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 (wang yang)) ying hua tan xin ji ((shang kai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yan) OR (wang yang)) ying hua tan xin ji ((shang kai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yan) OR (wang yang)) ying hua tan xin ji ((shang kai) or (hong hai)) ;*.
