Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va, hieu ve
cham xuc » chat xuc, cham soc, pham duc
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, va danh
hanh ve » hanh vi, hanh va, hanh kem
cau tre » cau tren, cau treo, cau tra
y nang » ky nang, ly nang, v nang
ve cau » ke cau, va cau, ve cac

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

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