Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
manh hung » anh huong
dap nhung » vap nhung, va nhung, dap ung
chi hanh » chi nhanh, chi thanh, thi hanh
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan ban » van ban
doi chi » doi khi

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: doi chi hanh - ((sinh trung) OR (manh hung)) dap nhung cong tan toan ban~.
• Adding a wildcard symbol may retrieve word variants: doi chi hanh - ((sinh trung) or (manh hung)) dap nhung cong tan toan ban*.
