Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cac tuc » cac toc, cac tu, cac tac
van anh » van thanh, van minh
so viet » hoc viet
su cac » tu cac, su cao, su can
ve cac » va cac, vien cac
tuan » quan, tran, luan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su cac ky nang xa hoi. hieu ve cac tuc ((van anh) or (tuan anh)) vai ((su viet) OR (so viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac ky nang xa hoi. hieu ve cac tuc ((van anh) OR (tuan anh)) vai ((su viet) OR (so viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac ky nang xa hoi. hieu ve cac tuc ((van anh) or (tuan anh)) vai ((su viet) OR (so viet))*".
