Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
hieu van » hieu va, thien van, lieu va
hanh di » hanh vi, hanh de, hang di
van cau » van dau, van hau, van chat
tu sach » thu sach, su sach, te sach
ly nang » ky nang, ly hang, ly vang
y nang » ky nang, v nang, may nang
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
di su » doi su, ki su, da su

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 sach ((y nang) OR (ly nang)) xa hoi. hieu van cau ((xuc va) OR (luc va)) hanh di su triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (ly nang)) xa hoi. hieu van cau ((xuc va) or (luc va)) hanh di su triet*.
