Perhaps you should try some spelling variations:
va trien » va truyen, va thiet, va tuyen
va triet » va thiet, ve triet, cua triet
van dinh » van minh, van dich, va dinh
xuc van » duc van, luc van, vuc van
dinh su » dinh so, hinh su, dinh cu
te sach » toc sach
hieu ve » hieu va, hieu van
ty nang » ky nang, ty hang, ly nang
ve cam » ve cham, ve cac, va cam

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