cong ghi » hong ghi, cong shu
dong di » dong sin
ya a » y a, ye a, 1a a
yu a » you a, eu a, ou a
u a » up a, eu a, uk a
a a » a la
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yan) or (dong di)) ((((ya a) or (((yu a) OR (u a))))) or (a a)) brain sang minh cong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (dong di)) ((((ya a) OR (((yu a) OR (u a))))) OR (a a)) brain sang minh cong ghi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong di)) ((((ya a) or (((yu a) OR (u a))))) or (a a)) brain sang minh cong ghi ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dong di)) ((((ya a) or (((yu a) OR (u a))))) or (a a)) brain sang minh cong ghi ;*.
