Perhaps you should try some spelling variations:
thanh dung » thanh duong, thanh tung, thanh hung
cong luong » cong thuong, nang luong, cong dong
doi chieu » doc hieu, doi chi, mot chieu
ho chieu » theo chieu, hoc thieu, mot chieu
dung cua » dung luan, dung cho
dan than » dan chan, van than, dan toan
ban than » ban thanh, van thanh, ban hang

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 chieu) OR (ho chieu)) xanh - thanh dung cua cong luong ((dan than) OR (ban than)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) OR (ho chieu)) xanh - thanh dung cua cong luong ((dan than) or (ban than)) cap~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) OR (ho chieu)) xanh - thanh dung cua cong luong ((dan than) or (ban than)) cap*.
