Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hang vi » hang va, hanh vi, hang di
cau tra » ca tra, cau ra, cau truc
tu ban » thu ban, te ban
ban ky » van ky, dan ky
va cau » van cau, va cac, va dau
luc va » duc va, loc va
tuc va » thuc va, truc va, tuc xa
vi cau » ve cau, di cau, viet cau

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: tu ban ky nang xa hoi. lieu va cau ((luc va) OR (tuc va)) hang vi cau tra~.
• Adding a wildcard symbol may retrieve word variants: tu ban ky nang xa hoi. lieu va cau ((luc va) or (tuc va)) hang vi cau tra*.
