Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cua viet » ca viet, hoa viet, cua vat
tu sach » thu sach, su sach, te sach
nang ma » tang ma, sang ma, nang cao
cau xuc » cau luc, cau truc, chat xuc
dan dai » dat dai, can dai, dan dat
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa
va dan » ca dan, va dao, va dau

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 ma hoi. hieu van ((cau xuc) OR (cam xuc)) va dan dai cua viet~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ma hoi. hieu van ((cau xuc) or (cam xuc)) va dan dai cua viet*.
