Perhaps you should try some spelling variations:
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
va hanh » van hanh, va thanh, va danh
hieu va » lieu va, hieu qua
nang ma » tang ma, sang ma, nang cao
tu sach » thu sach, su sach, te sach
ma hoi » mai hoi, xa hoi, ma hoa
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
tu sac » tu cac, tu san, tu bac

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 sac) OR (tu sach)) ky nang ma hoi. hieu va cam xuc va hanh vi ((cua tre) OR (cuu tre))~.
• Adding a wildcard symbol may retrieve word variants: ((tu sac) or (tu sach)) ky nang ma hoi. hieu va cam xuc va hanh vi ((cua tre) or (cuu tre))*.
