Perhaps you should try some spelling variations:
te sach » toc sach
nang xa » nang x, lang xa, nang ma
vu cham » va cham, vu kham, tu cham
va hanh » van hanh, va thanh, va danh
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
loc va » hoc va, luc va

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