Perhaps you should try some spelling variations:
trinh cong » trinh dung
lanh manh » lanh tranh, lan anh, van manh
qua trinh » qua kinh
ho trieu » mot trieu, 25 trieu, 30 trieu
manh qua » manh quan, manh cua, danh qua
cong san » cong tac
toan cau » toan cao, 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: ho trieu tinh - lanh manh qua trinh cong san ((((toan cau) OR (toan ban))) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - lanh manh qua trinh cong san ((((toan cau) OR (toan ban))) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - lanh manh qua trinh cong san ((((toan cau) OR (toan ban))) or (toan tap))*.
