Perhaps you should try some spelling variations:
nam thuc » nam thuoc, am thuc, nam thu
te sach » toc sach
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
cam tuc » cam xuc, dam thuc, nam truc
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang
cam tu » cam thu, nam tu, dam tu
vi cua » vai cua, di cua

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 xa hoi. hieu ve ((((cam tuc) OR (cam tu))) or (nam thuc)) va hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. hieu ve ((((cam tuc) OR (cam tu))) OR (nam thuc)) va hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. hieu ve ((((cam tuc) OR (cam tu))) or (nam thuc)) va hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. hieu ve ((((cam tuc) OR (cam tu))) or (nam thuc)) va hanh vi cua tre*.
