Perhaps you should try some spelling variations:
tieu dung » dieu duong, tin dung, viet dung
cac khoi » cac thoi, cac khoan, cach thoi
cac khu » cac kieu
cac thu » cach thuc, cac thoi
te dung » tien dung, tin dung, tac dung
ban ve » ban va
ve y » ve ky, ve _, ke y
tuyen » truyen, quyen

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tuyen tap ((((cac khu) OR (cac khoi))) or (cac thu)) đe co ban ve y ((te dung) or (tieu dung)) cong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((((cac khu) OR (cac khoi))) OR (cac thu)) đe co ban ve y ((te dung) OR (tieu dung)) cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((((cac khu) OR (cac khoi))) or (cac thu)) đe co ban ve y ((te dung) or (tieu dung)) cong".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((cac khu) OR (cac khoi))) or (cac thu)) đe co ban ve y ((te dung) or (tieu dung)) cong*.
