Perhaps you should try some spelling variations:
thanh viec » thanh vien, thanh liem, thanh nien
hieu nghe » lieu nghe, hiem ngheo, nhiem nghe
nghe nam » nghe lam, nghiep nam, nghe nano
thuc dan » hoc dan, thuc vat
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky ((nang xa) OR (lang xa)) hoi. hieu nghe nam ((thuc dan) or (thuc hanh)) thanh viec cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky ((nang xa) OR (lang xa)) hoi. hieu nghe nam ((thuc dan) OR (thuc hanh)) thanh viec cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky ((nang xa) OR (lang xa)) hoi. hieu nghe nam ((thuc dan) or (thuc hanh)) thanh viec cua te".
• Adding a wildcard symbol may retrieve word variants: vu sac ky ((nang xa) OR (lang xa)) hoi. hieu nghe nam ((thuc dan) or (thuc hanh)) thanh viec cua te*.
