Perhaps you should try some spelling variations:
cua phuong » cuu phuong, cuc phuong, luan phuong
cang thang » cong thanh, dang thanh
theo phap » thi phap
phap tinh » phap sinh, phap tieng, phap tang
cua khong » hua khong, cua thuong, cua cong
cong tac » cong ty
tac toan » tap toan, tam toan, hach toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "theo phap tinh - cang thang ((cua khong) OR (cua phuong)) cong tac toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo phap tinh - cang thang ((cua khong) OR (cua phuong)) cong tac toan cau*.
