shang kai » shang hai
zhong zhi » zhang zhi, hong ghi, zhong tai
lang yan » wang yan, wang yang, zhang yan
yan yang » yang yang, yao yang, dan yang
yang hua » wang hua, yang hui, ying hua
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 yang hua tan xin ji ((shang kai) OR (zhong zhi)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan yang hua tan xin ji ((shang kai) or (zhong zhi)) ;*.
