Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cua viet » hoa viet, cua vat, cua dieu
thanh vi » hanh vi, thanh va, thanh ve
tu sach » thu sach, su sach, te sach
xuc ban » duc ban, cuc ban, quoc ban
cac xuc » cam xuc, cac nuoc, chat xuc
hieu va » lieu va, hieu qua
ca viet » va viet, co viet, hoa viet
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang

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 (v nang)) xa hoi. hieu va cac xuc ban thanh vi ((cua viet) OR (ca viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) or (v nang)) xa hoi. hieu va cac xuc ban thanh vi ((cua viet) OR (ca viet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) or (v nang)) xa hoi. hieu va cac xuc ban thanh vi ((cua viet) OR (ca viet))*.
