Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
hanh dung » thanh dung, anh dung, hanh dong
cua khong » hua khong, cua phuong, cua thuong
thu sang » thu hang, thu san, thu bang
chu bang » thu bang, chuc nang, chu quang
dung cua » dung luan, dung cho
dan toan » van toan, dan than, manh toan

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 ((thu sang) OR (chu bang)) - hanh dung cua khong cong ((dan toan) OR (tinh toan)) cao~.
• Adding a wildcard symbol may retrieve word variants: theo ((thu sang) or (chu bang)) - hanh dung cua khong cong ((dan toan) or (tinh toan)) cao*.
