Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, pham duc
hanh va » hang va, hanh vi
va hanh » van hanh, va thanh, va danh
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
va cuu » va cau, va chu, va huu

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) OR (toc sach)) y nang xa hoi. hieu ve ((cham xuc) or (cham soc)) va hanh va cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) y nang xa hoi. hieu ve ((cham xuc) OR (cham soc)) va hanh va cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) y nang xa hoi. hieu ve ((cham xuc) or (cham soc)) va hanh va cuu tre*".
