Perhaps you should try some spelling variations:
nang han » nang phan, nang hang, nang hanh
va hanh » van hanh, va thanh, va danh
nang ha » nang hai, nang hoa, lang ha
cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua
vi cua » vai cua, di cua
xuc va » duc va, tuc va, luc va
xac ky » cac ky, sac ky
bac ky » cac ky, ban ky, sac ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((xac ky) OR (bac ky)) ((nang ha) or (nang han)) hoi. hieu va cac xuc va hanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((xac ky) OR (bac ky)) ((nang ha) OR (nang han)) hoi. hieu va cac xuc va hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((xac ky) OR (bac ky)) ((nang ha) or (nang han)) hoi. hieu va cac xuc va hanh vi cua te*".
