Perhaps you should try some spelling variations:
vay doanh » ly doanh, voi doanh, von doanh
van doanh » toan doanh, van dong, van thanh
doanh tri » doanh tai, doanh tren, dinh tri
dai doanh » dai danh, dao doanh, doi doanh
vien dai » hien dai
cao dan » cao dang, cao danh, cac dan
dan tai » van tai, dan thi, han tai
te cao » te bao

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( te ((vay doanh) OR (van doanh)) tri ) OR ((( te cao dan tai ) OR ( vien dai doanh tri ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te ((vay doanh) OR (van doanh)) tri ) or ((( te cao dan tai ) or ( vien dai doanh tri ))))~".
• Adding a wildcard symbol may retrieve word variants: (( te ((vay doanh) OR (van doanh)) tri ) or ((( te cao dan tai ) or ( vien dai doanh tri ))))*.
