Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
tu sach » thu sach, su sach, te sach
cua tre » cua te, cua triet, dua tren
dinh vi » dinh ve, dinh viet, dinh tri
va dinh » van dinh, va kinh, va tinh
cao xuc » cam xuc, cao duc, cao suc
tang xa » trang xa, tang ma, lang xa
ky tang » ky nang, ky dang, kho tang
cuu tre » cau tren, cau treo
va cao » va cac, va co, va dao
xuc va » duc va, tuc va, luc va

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) OR (thuat sach)) ky tang xa hoi. lieu va cao xuc va dinh vi ((cua tre) OR (cuu tre))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thuat sach)) ky tang xa hoi. lieu va cao xuc va dinh vi ((cua tre) OR (cuu tre))~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thuat sach)) ky tang xa hoi. lieu va cao xuc va dinh vi ((cua tre) OR (cuu tre))*.
