Perhaps you should try some spelling variations:
thieu vien » thieu nien, thieu bien, thu vien
ve triet » va trien
su triet » su viet, su tien
hanh via » hanh vi, hanh va, anh va
van hanh » van thanh, ban hanh, van anh
xuc van » duc van, luc van, vuc van
nang ma » tang ma, sang ma, nang cao
vien da » vien dai, hien dai
ma hoi » mai hoi, xa hoi, ma hoa
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 ((sach y) or (sac ky)) nang ma hoi. thieu vien da xuc van hanh via ((su triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach y) OR (sac ky)) nang ma hoi. thieu vien da xuc van hanh via ((su triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach y) or (sac ky)) nang ma hoi. thieu vien da xuc van hanh via ((su triet) OR (ve triet))*".
