Perhaps you should try some spelling variations:
ban doanh » van doanh, san doanh, toan doanh
ban danh » ban hanh, ban dan, van danh
vu sach » vu bach, su sach, vu khach
so sanh » do sanh
hieu va » lieu va, hieu qua
tai cuu » tai cuc, tai buu, tai cua
cuu tre » cua tre, cau tren, cau treo
nang o » nang co, nang ho, nang ro
va cam » va cham, va cac, va cao
o hoi » co hoi, o hoc, o hai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (so sanh)) ky nang o hoi. hieu va cam xuc ((ban danh) OR (ban doanh)) tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (so sanh)) ky nang o hoi. hieu va cam xuc ((ban danh) OR (ban doanh)) tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (so sanh)) ky nang o hoi. hieu va cam xuc ((ban danh) OR (ban doanh)) tai cuu tre*".
