Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
luan dong » luan cong, quan dong, luan nong
dong cong » duong cong, dung cong, dang cong
cua tinh » va tinh, ha tinh, hoa tinh
cua sinh » hoa sinh, va sinh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cao » toan ban, toan tap

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 ((((cua tinh) OR (cua sinh))) OR (trieu tinh)) - hanh dung luan dong cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((((cua tinh) OR (cua sinh))) or (trieu tinh)) - hanh dung luan dong cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: theo ((((cua tinh) OR (cua sinh))) or (trieu tinh)) - hanh dung luan dong cong dan toan cao*.
