Perhaps you should try some spelling variations:
mieng » tieng, mien, rieng
mang » nang, dang, bang
han » phan, hanh, hang
nphanh » npphanh, nphanhh, nphangh, nhanh, phanh
khanh » kphanh, khanhh, khangh, thanh, hanh
nhang » nphang, nhanhg, nhangg, nhung, nang, hang, phang
nhan » nphan, nhanh, nhang, phan

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: emperor (mieng OR mang) of (han OR (((nphanh OR khanh) OR (nhang OR nhan)) OR nganh))~.
• Adding a wildcard symbol may retrieve word variants: emperor (mieng or mang) of (han or (((nphanh or khanh) or (nhang or nhan)) or nganh))*.
