Perhaps you should try some spelling variations:
van doanh » toan doanh, van dong, van thanh
doanh vi » doanh va, doan vi, doanh vien
hieu ve » hieu va, hieu van
cam cuu » cham cuu
ky lang » ky nang, ky dang, ky tang
van hoi » van hoa, van hoc, van loi
van hoe » van hoa, van hoc, van hieu
vi cua » vai cua, di cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
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 sac ky lang ((van hoi) OR (van hoe)). hieu ve ((cam cuu) or (cap cuu)) van doanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang ((van hoi) OR (van hoe)). hieu ve ((cam cuu) OR (cap cuu)) van doanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang ((van hoi) OR (van hoe)). hieu ve ((cam cuu) or (cap cuu)) van doanh vi cua te*".
