Perhaps you should try some spelling variations:
viec cac » viec cua, viec lam, viec va
van danh » van doanh, van anh, van hanh
vien cac » vien bach, vien dai, vien da
danh va » doanh va, hanh va, anh va
sach ty » sach tu, sach thu, xach tay
cuu tre » cua tre, cau tren, cau treo
nang xa » nang x, lang xa, nang ma
lo van » le van, vo van, so van
va cuu » va cau, va chu, va huu

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