Perhaps you should try some spelling variations:
va trien » va truyen, va thiet, va tuyen
cham duc » pham duc, cham soc, pham duy
ve triet » su triet
tri nang » thi nang, tra nang, tri bang
van hanh » van thanh, ban hanh, van anh
hanh de » hanh ve, hanh kem
duc van » duc va, duc tan, duc manh
tu cach » tu cac
hien tu » khien tu, dien tu
nang xa » nang x, lang xa, nang ma
te sach » toc sach
tu cham » toc cham, thi cham

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (te sach)) tri nang xa hoi. hien tu cham duc van hanh de ((ve triet) OR (va trien))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) tri nang xa hoi. hien tu cham duc van hanh de ((ve triet) OR (va trien))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (te sach)) tri nang xa hoi. hien tu cham duc van hanh de ((ve triet) OR (va trien))*".
