Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh, hoc dan, thuc vat
danh vai » danh sai, danh va, doanh van
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
hieu va » hieu qua
thuc va » thuc vat, thuc day
vai cua » dai cua, hai cua, lai cua
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 sach ky nang x hoi. ((hieu va) OR (lieu va)) am ((thuc va) OR (thuc dan)) danh vai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang x hoi. ((hieu va) OR (lieu va)) am ((thuc va) or (thuc dan)) danh vai cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang x hoi. ((hieu va) OR (lieu va)) am ((thuc va) or (thuc dan)) danh vai cua triet*.
