Perhaps you should try some spelling variations:
thu sach » tu sach, thuat sach, thuoc sach
cham xuc » chat xuc, cham soc, pham duc
hieu va » lieu va, hieu qua
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
hieu ve » 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
di cuu » di cau, di cua, dinh cuu

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y nang xa hoi. ((hieu ve) OR (hieu va)) ((cham xuc) or (cam xuc)) va hanh di cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang xa hoi. ((hieu ve) OR (hieu va)) ((cham xuc) OR (cam xuc)) va hanh di cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang xa hoi. ((hieu ve) OR (hieu va)) ((cham xuc) or (cam xuc)) va hanh di cuu tre*".
