Perhaps you should try some spelling variations:
viec cac » vien cac, viec va, ve cac
viec lam » viec va
van danh » van doanh, van anh, van hanh
danh vai » danh sai, danh va, doanh van
cau treo » cau theo, cau tren, cau triet
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
vai cau » va cau, van cau, vai cac
y nang » ky nang, ly nang, v nang
so van » su van, vo van

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 y nang xa hoi. hieu ((((viec cac) OR (viec lam))) or (viec cua)) so van danh vai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. hieu ((((viec cac) OR (viec lam))) OR (viec cua)) so van danh vai cau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((((viec cac) OR (viec lam))) or (viec cua)) so van danh vai cau treo*".
