Perhaps you should try some spelling variations:
theo phap » thi phap
phap tinh » phap sinh, phap tieng, phap tang
hanh tang » hanh trang, hanh mang, hanh tung
dung cong » dung trong
anh tang » anh bang, anh dang, anh nang
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong san, cong thanh
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: theo phap tinh - ((hanh tang) OR (anh tang)) cua dung cong tan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo phap tinh - ((hanh tang) OR (anh tang)) cua dung cong tan ((toan cau) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo phap tinh - ((hanh tang) OR (anh tang)) cua dung cong tan ((toan cau) or (toan ban))*.
