Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec coc » viec doc, viec cong, viec cuoi
va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, nang ma
vai cua » hai cua, bai cua, mai cua
lai cua » hai cua, lai chau, thai cua
vu san » va san, vu ban
san ky » sang ky, van ky, dan ky
luc va » duc va, tuc va, loc va

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 hoi. hieu viec coc luc va thanh ((((vai cua) OR (dai cua))) or (lai cua)) te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang xa hoi. hieu viec coc luc va thanh ((((vai cua) OR (dai cua))) OR (lai cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang xa hoi. hieu viec coc luc va thanh ((((vai cua) OR (dai cua))) or (lai cua)) te*".
