Perhaps you should try some spelling variations:
cong doanh » cong danh, cong doan, dong doanh
tang luan » dung luan
doanh cua » doanh luan
dung cong » dung trong
chi xanh » chi anh, chi danh, chi hanh
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap
doi chi » doi khi

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 ((tang luan) OR (doanh cua)) dung cong doanh ((phan cau) OR (phan cac))~.
• Adding a wildcard symbol may retrieve word variants: doi chi xanh - hanh ((tang luan) or (doanh cua)) dung cong doanh ((phan cau) or (phan cac))*.
