Perhaps you should try some spelling variations:
va trien » va truyen, va tuyen, va tieng
vu cham » va cham, vu kham, tu cham
va hanh » van hanh, va thanh, va danh
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, ve chim
hanh ky » hanh kem
te sac » te sach, te cac, te san
luc va » duc va, tuc va, loc va
sac ky » cac ky, sai ky
thiet » thieu

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. hieu ((ve cham) or (vu cham)) luc va hanh ky ((va trien) OR (va thiet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang xa hoi. hieu ((ve cham) OR (vu cham)) luc va hanh ky ((va trien) OR (va thiet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. hieu ((ve cham) or (vu cham)) luc va hanh ky ((va trien) OR (va thiet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ((ve cham) or (vu cham)) luc va hanh ky ((va trien) OR (va thiet))*.
