Perhaps you should try some spelling variations:
vien dai » hien dai
hanh dao » lanh dao, thanh dat, thanh dam
van hanh » van thanh, ban hanh, van anh
cua tre » cuu tre, cua triet, dua tren
xuc van » duc van, luc van, xuc ban
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
ve cam » ve cham, ve cac, va cam
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu ((ve cam) or (vien dai)) xuc van hanh dao ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu ((ve cam) OR (vien dai)) xuc van hanh dao ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu ((ve cam) or (vien dai)) xuc van hanh dao ((cua tre) OR (cua te))*".
