Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
viec cac » viec cua, viec va, ve cac
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
viec lam » viec va
vai cua » dai cua, hai cua, lai cua
luc van » luoc van, luu van, duc van
vu san » va san, vu ban
cua te » cua tu
san ky » sang ky, van ky, dan ky
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) OR (viec lam))) or (vien cac)) luc van hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky nang x hoi. hieu ((((viec cac) OR (viec lam))) OR (vien cac)) luc van hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky nang x hoi. hieu ((((viec cac) OR (viec lam))) or (vien cac)) luc van hanh vai cua te*".
