Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
viec cac » viec cua, viec lam, viec va
hanh vai » hanh va, hanh tai, hanh van
nang xa » nang x, lang xa, nang ma
vu san » va san, vu ban
luc va » duc va, tuc va, loc va
san ky » sang ky, van ky, dan ky
cua te » cua tu

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