phan » pnhan, phang, pthan
nphan » npnhan, nphang, npthan, nhan
hanh » nhanh, hangh, thanh, anh
phanh » pnhanh, phangh, pthanh, panh, thanh, khanh, nhanh
hinh » dinh, minh, kinh
chinh » cdinh, cminh, ckinh
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 phan) or nphan) or ((hanh OR hinh) or ((phanh or chinh) or phong))) dynasty~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((han OR phan) OR nphan) OR ((hanh OR hinh) OR ((phanh OR chinh) OR phong))) dynasty.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((han or phan) or nphan) or ((hanh OR hinh) or ((phanh or chinh) or phong))) dynasty".
• Adding a wildcard symbol may retrieve word variants: (((han or phan) or nphan) or ((hanh OR hinh) or ((phanh or chinh) or phong))) dynasty*.
