Perhaps you should try some spelling variations:
dinh lai » dinh lam, dinh lap, dinh tai
te sach » toc sach
cua tre » cua te, cua triet, dua tren
va dinh » van dinh, va kinh, va tinh
van cau » van dau, van hau, van chat
van cam » van nam, van lam, van dam
nang ma » tang ma, sang ma, nang cao
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ma hoi. thien ((van cam) or (van cau)) duc va dinh lai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ma hoi. thien ((van cam) OR (van cau)) duc va dinh lai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ma hoi. thien ((van cam) or (van cau)) duc va dinh lai ((cua tre) OR (cuu tre))*".
