Perhaps you should try some spelling variations:
doanh quan » doanh quang, doanh luan, doan quan
luong cong » dung cong, trong cong, cong cong
doanh qua » doanh cua, danh qua, doanh quang
chi xanh » chi anh, chi danh, chi hanh
cong dan » cong san, cong tan, huong dan
dan thai » dang thai, dan thi, dan than
thai cao » tai cao, thoai cac, thuat cao

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: doi chi xanh - hanh ((doanh qua) OR (doanh quan)) luong cong dan thai cao~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh ((doanh qua) or (doanh quan)) luong cong dan thai cao*.
