dan yang » daun yang, tan yang, wang yang
hui hong » hui tong, hai phong, hua zhong
tan hua » wang hua, tan chia, tan puay
hu hong » hou hong, hu yong, hua zhong
wang » wing, wan, lang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yanling) OR (yang yang)) ((tuan hua) OR (tan hua)) dan yang ((hui hong) OR (hu hong)) hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yanling) or (yang yang)) ((tuan hua) or (tan hua)) dan yang ((hui hong) OR (hu hong)) hai ;*".
