thanh » tphanh, thangh, tthanh, tanh, thinh
panh » phanh, anh, danh
phinh » chinh, hinh, thinh
phong » thong

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((han or (nphan OR nhan)) or ((hanh or thanh) or (((panh or phinh) or phinh) or phong))) dynasty~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((han OR (nphan OR nhan)) OR ((hanh OR thanh) OR (((panh OR phinh) OR phinh) OR phong))) dynasty.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((han or (nphan OR nhan)) or ((hanh or thanh) or (((panh or phinh) or phinh) or phong))) dynasty".
• Adding a wildcard symbol may retrieve word variants: ((han or (nphan OR nhan)) or ((hanh or thanh) or (((panh or phinh) or phinh) or phong))) dynasty*.
