Perhaps you should try some spelling variations:
va triet » va thiet, va trien, cua triet
ve triet » va trien, su triet
xang xa » lang xa, mang xa, ang xa
sach ty » sach tu, sach thu, xach tay
va hanh » van hanh, va thanh, va danh
hanh di » hanh vi, hanh de, hang di
cam tuc » cam xuc, cam tu, nam thuc
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach ty) or (sach y)) xang xa hoi. lieu va cam tuc va hanh di ((va triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach ty) OR (sach y)) xang xa hoi. lieu va cam tuc va hanh di ((va triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach ty) or (sach y)) xang xa hoi. lieu va cam tuc va hanh di ((va triet) OR (ve triet))".
• Adding a wildcard symbol may retrieve word variants: thuat ((sach ty) or (sach y)) xang xa hoi. lieu va cam tuc va hanh di ((va triet) OR (ve triet))*.
