Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
viec cam » viec lam, viec cua, viec va
danh vai » danh sai, danh va, doanh van
nang ma » tang ma, nang cao, mang may
sang ma » tang ma, sang tao, mang may
va danh » va dinh, va dan, va hanh
vu san » va san, vu ban
xuc va » duc va, tuc va, luc va
san ky » sang ky, van ky, dan ky
cua tu » cua tuc, cua su, cua cu

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 ma) OR (sang ma)) hoi. nhieu viec cam xuc va danh vai ((cua te) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky ((nang ma) OR (sang ma)) hoi. nhieu viec cam xuc va danh vai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky ((nang ma) OR (sang ma)) hoi. nhieu viec cam xuc va danh vai ((cua te) or (cua tu))*".
