Perhaps you should try some spelling variations:
theo chuc » theo chu, tho chu, treo chu
hanh hang » thanh hang, hang hang, hanh han
cua khong » hua khong, cua phuong, cua thuong
cua tong » cua cong, cua dong, cua nong
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than man » than ma, thanh san, tran manh

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 hang ((cua khong) OR (cua tong)) cong tan than man~.
• Adding a wildcard symbol may retrieve word variants: theo chuc nang - hanh hang ((cua khong) or (cua tong)) cong tan than man*.
