Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
hanh lam » thanh lap, hanh kem, hanh va
thi hanh » thi thanh
thuc dan » thuc hanh, hoc dan, thuc vat
hai cuu » hai cua, hai chu, hai cuc
thuc va » thuc vat, thuc day
cuu tre » cua tre, cau tren, cau treo
tang ma » mang may, tang van
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 ((tang ma) or (hang va)) hoi. thi hanh lam ((thuc va) OR (thuc dan)) thanh hai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((tang ma) OR (hang va)) hoi. thi hanh lam ((thuc va) OR (thuc dan)) thanh hai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((tang ma) or (hang va)) hoi. thi hanh lam ((thuc va) OR (thuc dan)) thanh hai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sac ky ((tang ma) or (hang va)) hoi. thi hanh lam ((thuc va) OR (thuc dan)) thanh hai cuu tre*.
