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