Perhaps you should try some spelling variations:
cau tren » cu tren, dau tren, ca tren
van danh » van doanh, van anh, van hanh
viec cac » vien cac, viec lam, viec va
danh vai » danh sai, danh va, doanh van
cuu tre » cua tre, cau treo
te sach » toc sach
sach ky » sac ky, sach y, sach ty
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
lo van » le van, vo van, so van

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 ky lang xa hoi. nhieu ((viec cac) or (viec cua)) lo van danh vai ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang xa hoi. nhieu ((viec cac) OR (viec cua)) lo van danh vai ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang xa hoi. nhieu ((viec cac) or (viec cua)) lo van danh vai ((cuu tre) OR (cau tren))*".
