Perhaps you should try some spelling variations:
han » nhan, than, hoan
hanh » nhanh, thanh, hoanh, anh, hinh
nthanh » ntnhanh, ntthanh, nthoanh, ntanh, nthinh, thanh
nhanh » nnhanh, nthanh, nhoanh, nanh, nhinh, thanh, nganh, nhan
phang » pnhang, pthang, phoang, phong, thang, phung, pnang, pdang, pbang
hang » nhang, thang, hoang, nang, dang, bang
phan » pnhan, pthan, phoan
khangh » knhangh, kthangh, khoangh, knangh, kdangh, kbangh, khanh, khang

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (han OR ((hanh OR (nthanh OR nhanh)) OR ((phang OR hang) OR (phan OR khangh)))) dynasty~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(han or ((hanh or (nthanh or nhanh)) or ((phang OR hang) or (phan or khangh)))) dynasty~".
• Adding a wildcard symbol may retrieve word variants: (han or ((hanh or (nthanh or nhanh)) or ((phang OR hang) or (phan or khangh)))) dynasty*.
