Perhaps you should try some spelling variations:
cong cong » cong dong, trong cong, dung cong
cac thu » cach thuc, cac thoi
te cong » tai cong, thi cong, thu cong
cac chu » cac khu, ca chu, cac cau
cac che » cac he, cac chien, cac chat
ve ky » va ky, ke ky
ve y » ve _, ke y, te 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 chu) or (cac che))) or (cac thu)) đe co ban ((ve y) OR (ve ky)) te cong cong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((((cac chu) OR (cac che))) OR (cac thu)) đe co ban ((ve y) OR (ve ky)) te cong cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((((cac chu) or (cac che))) or (cac thu)) đe co ban ((ve y) OR (ve ky)) te cong cong".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((cac chu) or (cac che))) or (cac thu)) đe co ban ((ve y) OR (ve ky)) te cong cong*.
