Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
viec cam » viec lam, viec cua, viec va
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, bai cua
lai cua » dai cua, hai cua, lai chau
vu san » va san, vu ban
san ky » sang ky, van ky, dan ky
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va

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 san ky nang xa hoi. nhieu viec cam ((xuc va) OR (luc va)) hanh ((vai cua) OR (lai cua)) te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. nhieu viec cam ((xuc va) or (luc va)) hanh ((vai cua) OR (lai cua)) te~".
• Adding a wildcard symbol may retrieve word variants: vu san ky nang xa hoi. nhieu viec cam ((xuc va) or (luc va)) hanh ((vai cua) OR (lai cua)) te*.
