Perhaps you should try some spelling variations:
thanh doi » thanh loi, thanh moi, thanh do
thanh di » thanh de, thanh do, thanh dinh
nay thuc » nam thuc, cay thuc, day thuc
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
thuc va » thuc vat, thuc dan, thuc day
nang ma » tang ma, sang ma, nang cao
sai ky » sac ky
va nay » va ngay, va cay
ma hoi » mai hoi, xa hoi, ma hoa
tu sai » tu bai, tu san, tu cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky nang ma hoi. lieu va nay thuc va ((thanh di) OR (thanh doi)) ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky nang ma hoi. lieu va nay thuc va ((thanh di) OR (thanh doi)) ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky nang ma hoi. lieu va nay thuc va ((thanh di) OR (thanh doi)) ((cua tre) or (cuu tre))*".
