Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
va thanh » gia thanh, ban thanh, va tinh
viec cac » vien cac, viec cua, viec lam
va hanh » van hanh, va danh, ban hanh
nang xa » nang x, lang xa, nang ma
cac luc » cau luc, coc luc, cac nuoc
vai cua » dai cua, hai cua, lai cua
van anh » van thanh, tuan anh, van minh
vu ban » tu ban, va ban
ban 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 ban ky nang xa hoi. hieu viec cac luc ((((va hanh) OR (va thanh))) or (van anh)) vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ban ky nang xa hoi. hieu viec cac luc ((((va hanh) OR (va thanh))) OR (van anh)) vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ban ky nang xa hoi. hieu viec cac luc ((((va hanh) OR (va thanh))) or (van anh)) vai cua te*".
