Perhaps you should try some spelling variations:
thanh moi » thanh loi, thanh hoa, thanh hai
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
nam thuc » nam thuoc, am thuc, nam thu
va thanh » gia thanh, ban thanh, va tinh
thuc va » thuc vat, thuc dan, thuc day
hieu va » lieu va
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
sac ky » cac ky, sai ky
te sac » te sach, te cac, te san

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang xa hoi. ((hieu va) or (hieu qua)) nam thuc va thanh moi ((cua triet) OR (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang xa hoi. ((hieu va) OR (hieu qua)) nam thuc va thanh moi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang xa hoi. ((hieu va) or (hieu qua)) nam thuc va thanh moi ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky lang xa hoi. ((hieu va) or (hieu qua)) nam thuc va thanh moi ((cua triet) OR (cua viet))*.
