Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
sach ky » sac ky, sach y, sach ty
va hanh » van hanh, va thanh, va danh
su sach » so sach, vu sach
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
ve cam » ve cham, va cam, ve cai
xuc va » duc va, tuc va, luc va
ve cac » va cac, vien cac

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

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