• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((yuan yan) or (yuan yang)) hui li dai han wen da xi. ) or ( ((guan yuan) OR (yuan yuan)) hua de li tan wen da xi. ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((yuan yan) or (yuan yang)) hui li dai han wen da xi. ) or ( ((guan yuan) OR (yuan yuan)) hua de li tan wen da xi. ))*.
