Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
cac cong » cua cong
cong ban » cong bang, cong san, cong tan
thanh vi » hanh vi, thanh va, thanh ve
ve triet » su triet
va trien » va truyen, va thiet, va tieng
va tuyen » va truyen, tac tuyen, ke tuyen
nang xa » nang x, lang xa, nang ma
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang xa hoi. lieu va cac cong ban thanh vi ((ve triet) or (((va trien) OR (va tuyen))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. lieu va cac cong ban thanh vi ((ve triet) OR (((va trien) OR (va tuyen)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. lieu va cac cong ban thanh vi ((ve triet) or (((va trien) OR (va tuyen))))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. lieu va cac cong ban thanh vi ((ve triet) or (((va trien) OR (va tuyen))))*.
