Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dinh bat » danh bat, dinh ba, dinh dat
tu sach » thu sach, su sach, te sach
nang co » nang cao, nang doc, nang noi
thuc va » thuc dan, thuc day
bat cua » ban cua, mat cua, bai cua
y nang » ky nang, ly nang, v nang
co hoi » co hoc, co loi
va lam » van lam, va lap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang co hoi. lieu va lam ((thuc va) OR (thuc vat)) dinh bat cua triet~".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang co hoi. lieu va lam ((thuc va) OR (thuc vat)) dinh bat cua triet*.
