Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
phan cong » thanh cong
chao chu » cho chu, cua chu, cao cho
chu tinh » chau tinh, chua tinh, cuu tinh
han cong » hang cong, hanh cong, han tong
toan cau » toan cao, toan tap, toan tai
toan ban » van 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: chao chu tinh - hanh dung luan ((han cong) OR (phan cong)) dan ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: chao chu tinh - hanh dung luan ((han cong) or (phan cong)) dan ((toan cau) or (toan ban))*.
