Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cuu tre, cua triet, dua tren
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va
cua te » cua tu

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 ty nang ma hoi. hieu va cac xuc va ((danh cho) OR (dan ca)) ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty nang ma hoi. hieu va cac xuc va ((danh cho) or (dan ca)) ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang ma hoi. hieu va cac xuc va ((danh cho) or (dan ca)) ((cua tre) OR (cua te))*.
