Perhaps you should try some spelling variations:
cua thuoc » nha thuoc, cay thuoc, cua quoc
danh sai » dung sai, danh bat, danh dau
ve triet » va trien, su triet
cua nuoc » cua quoc, cua nguoi, nha nuoc
te sach » toc sach
sach ky » sac ky, sach y, sach ty
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
lam xuc » cam xuc, lam duoc
va danh » va dinh, va dan, va hanh
va lam » van lam, va lap
xuc va » duc va, tuc va, luc va

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: te sach ky lang xa hoi. lieu va lam xuc va danh sai ((ve triet) OR (((cua thuoc) OR (cua nuoc))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. lieu va lam xuc va danh sai ((ve triet) or (((cua thuoc) OR (cua nuoc))))~".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang xa hoi. lieu va lam xuc va danh sai ((ve triet) or (((cua thuoc) OR (cua nuoc))))*.
