how to import the binary dump sql in MySQL 5.7

Today I received a binary sql dump script efs_bbs.sql(MySQL 5.7),then I open it with text editor, it looks like this:

b#eHE-SafeNetLOCKΩA®@¨g%;ägWnímã˛~Q5åÔÔÃÄÜ)hT(ı=≥ùOf2Æ  ÔCf‹flo

what should I do to import the sql to my database? I have tried this command:

mysql: (Warning) Using a password on the command line interface can be insecure.
ERROR at line 1: Unknown command '?'.

any other way to import? Am I doing wrong way?
