Perhaps you should try some spelling variations:
cong cong » cong dong, trong cong, dung cong
cach thuc » anh thuc, cac thu
cac khoi » cac thoi, cac khoan, cach thoi
ban kem » banh kem, hanh kem, banh keo
te cong » tai cong, thi cong, thu cong
ban ke » ban ve, ban le, ban ky
tuyen » truyen, quyen

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: tuyen tap ((((cac khoi) OR (cac he))) OR (cach thuc)) đe co ((ban kem) OR (ban ke)) y te cong cong~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((((cac khoi) or (cac he))) or (cach thuc)) đe co ((ban kem) OR (ban ke)) y te cong cong~".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((((cac khoi) or (cac he))) or (cach thuc)) đe co ((ban kem) OR (ban ke)) y te cong cong*.
