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