Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan
bach tu » bach thu, cach tu, bac tu
tu nang » tru nang, tu nong, tu nano
nang ma » tang ma, sang ma, nang cao
hieu va » lieu va, hieu qua
va pham » van pham, va phat, va phap
danh tu » anh tu, doanh thu
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 pham ((thuc vat) OR (thuc dan)) danh tu cua te~.
• Adding a wildcard symbol may retrieve word variants: vu bach tu nang ma hoi. hieu va pham ((thuc vat) or (thuc dan)) danh tu cua te*.
