yang hua » wang hua, yang hui, ying hua
fan ying » fan xing, ran ying, tan ying
tan yang » dan yang, tan ying, tan yong
hong hai » shang hai, zhong tai, hong tan
wang » wing, wan, lang

• Adding a wildcard symbol may retrieve word variants: wang yan yang hua ((fan ying) or (tan yang)) ji ((dang hai) or (hong hai)) ;*.
