Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
can thuc » dan thuc, van thuc, cay thuc
va hanh » van hanh, va thanh, va danh
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va, hieu qua
hieu ve » hieu van
tu sach » thu sach, su sach, te sach
va nang » van nang, da nang, cam nang
v nang » vu nang, van nang, voi nang
vi cua » vai cua, di cua

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: tu sach ((v nang) OR (va nang)) xa hoi. ((hieu ve) OR (hieu va)) can thuc va hanh vi cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu sach ((v nang) or (va nang)) xa hoi. ((hieu ve) or (hieu va)) can thuc va hanh vi cua triet*.
