Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc van » thuc vat, thuc dan, thuc va
van hanh » van thanh, ban hanh, van anh
su sach » so sach, vu sach
sach vu » sach va, sach tu, sach uu
vu nang » vuc nang, va nang, vu dang
van lam » van nam
van am » van nam, van dam, van ai
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, 5 hoi

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 vu nang ((x hoi) OR (x ho)). hieu ((van am) or (van lam)) thuc van hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach vu nang ((x hoi) OR (x ho)). hieu ((van am) OR (van lam)) thuc van hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach vu nang ((x hoi) OR (x ho)). hieu ((van am) or (van lam)) thuc van hanh vi cua triet*".
