Perhaps you should try some spelling variations:
hung thang » cang thang, hung tran
theo phap » thi phap
phap tinh » phap sinh, phap tieng, phap tang
cua khong » cua phuong, cua thuong, cua cong
hua khong » hoa khong, hoac khong, phuc khong
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 tinh - hung thang ((cua khong) OR (hua khong)) cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo phap tinh - hung thang ((cua khong) OR (hua khong)) cong dan toan cau*.
