Perhaps you should try some spelling variations:
te sach » toc sach
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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

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