Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
hanh vai » hanh vi, hanh va, hanh van
hanh tai » thanh tai, hang tai, han tai
cua tuc » cua duc, cua tu, cua thuoc
vu san » va san, vu ban
san ky » sang ky, van ky, dan ky
loc va » hoc va, luc va
x hoi » xa hoi, o hoi, x ho

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 x hoi. hieu viec cac ((loc va) or (duc va)) ((hanh vai) OR (hanh tai)) cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang x hoi. hieu viec cac ((loc va) OR (duc va)) ((hanh vai) OR (hanh tai)) cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang x hoi. hieu viec cac ((loc va) or (duc va)) ((hanh vai) OR (hanh tai)) cua tuc*".
