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