Perhaps you should try some spelling variations:
cua thuong » cua truong, cua phuong, ca thuong
hung thang » cang thang, hung tran
theo phap » thi phap
phap sinh » phau sinh, phai sinh, phap tinh
cua khong » hua khong, cua phuong, cua cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh 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 sinh - hung thang ((cua khong) OR (cua thuong)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo phap sinh - hung thang ((cua khong) OR (cua thuong)) cong dan toan cau*.
