Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
bach tu » bach thu, cach tu, bac tu
danh tu » anh tu, doanh thu
thuc va » thuc vat, thuc day
tu nang » tru nang, tu nong, tu nano
hieu va » hieu qua
nang ma » tang ma, sang ma, nang cao
ma hoi » mai hoi, xa hoi, ma hoa
tu cua » hu cua, vu cua
cua te » cua tu

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: vu bach tu nang ma hoi. ((hieu va) OR (lieu va)) pham ((thuc va) OR (thuc dan)) danh tu cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach tu nang ma hoi. ((hieu va) OR (lieu va)) pham ((thuc va) or (thuc dan)) danh tu cua te~".
• Adding a wildcard symbol may retrieve word variants: vu bach tu nang ma hoi. ((hieu va) OR (lieu va)) pham ((thuc va) or (thuc dan)) danh tu cua te*.
