min hyoung » mun young
china tan » china top, china two, china taiwan
tan yang » dan yang, tan ying, tan yong

• The words AND, OR and NOT may confuse the search; try adding quotes: "land planning can china tan yang ((min hong) OR (min hyoung)) tan ;~".
• Adding a wildcard symbol may retrieve word variants: land planning can china tan yang ((min hong) OR (min hyoung)) tan ;*.
