Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec lam » viec va
van hanh » van thanh, ban hanh, van anh
nang xa » lang xa, nang ma, mang xa
lam duc » lam duoc, pham duc, nam duoc
va hanh » va thanh, va danh, ban hanh
vai cua » dai cua, hai cua, lai cua
vu san » va san, vu ban
san ky » sang ky, van ky, dan ky
cua cu » cua chu, cua cau, cua su

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu san ky ((nang xa) or (nang x)) hoi. hieu viec lam duc ((va hanh) OR (van hanh)) vai cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky ((nang xa) OR (nang x)) hoi. hieu viec lam duc ((va hanh) OR (van hanh)) vai cua cu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky ((nang xa) or (nang x)) hoi. hieu viec lam duc ((va hanh) OR (van hanh)) vai cua cu*".
