Perhaps you should try some spelling variations:
chinh doanh » kinh doanh
thieu sang » chieu sang, thieu khang, thieu quang
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
van doanh » toan doanh, van dong, van thanh
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan ban, toan tai
toan tap » toan ban

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: hoc thieu sang - ((chinh doanh) OR (van doanh)) va nhung cong dan ((toan cau) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sang - ((chinh doanh) or (van doanh)) va nhung cong dan ((toan cau) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu sang - ((chinh doanh) or (van doanh)) va nhung cong dan ((toan cau) OR (toan tap))*.
