Perhaps you should try some spelling variations:
vay doanh » van doanh, ly doanh, voi doanh
doanh tri » doanh tai, doanh tren, dinh tri
dai doanh » dai danh, dao doanh, doi doanh
van tuan » van quan, van ban, anh tuan
vien dai » hien dai
van tai » von tai
te vay » te va, te xay, te van
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 tri ) OR ((( te cao ((van tai) OR (van tuan)) ) OR ( vien dai doanh tri ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te vay doanh tri ) or ((( te cao ((van tai) OR (van tuan)) ) or ( vien dai doanh tri ))))~".
• Adding a wildcard symbol may retrieve word variants: (( te vay doanh tri ) or ((( te cao ((van tai) OR (van tuan)) ) or ( vien dai doanh tri ))))*.
