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