Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
xach tay » canh tay
hieu van » hieu va, thien van, lieu va
lam thuc » lam thuoc, am thuc, nam thuc
danh dai » danh dau, danh di, danh sai
van lam » van nam
thuc va » thuc vat, thuc dan, thuc day
va danh » va dinh, va dan, va hanh
x hoi » xa hoi, o hoi, x ho

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 ((xach tay) OR (sach y)) nang x hoi. hieu van lam thuc va danh dai cua triet~.
• Adding a wildcard symbol may retrieve word variants: tu ((xach tay) or (sach y)) nang x hoi. hieu van lam thuc va danh dai cua triet*.
