Perhaps you should try some spelling variations:
hanh trung » thanh trung, hanh trang, manh trung
phap thong » phap phong, pho thong, phap tieng
phap chong » phap phong, phap cong, pham hong
theo chuc » theo chu, tho chu, treo chu
cong san » cong tac
toan tai » toan tap, doanh tai, toan cao
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 chuc nang - hanh trung ((phap thong) OR (phap chong)) cong san ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chuc nang - hanh trung ((phap thong) OR (phap chong)) cong san ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chuc nang - hanh trung ((phap thong) OR (phap chong)) cong san ((toan tai) or (toan ban))*.
