１９８５年北京市地石律师事务所作为一家院校兼职所的建立，是改革开放政策的产物。我们认为，院校兼职所的性质决定这种事务所必须在为社会服务的同时，要为法学教育服务，办成法学院的教学实践基地。十几年来，我们始终坚持实行为社会服务和为法学教育服务相结合的办所宗旨 In 1985, Beijing Dashi Law Firm, as a part-time institute, was the product of the policy of reform and opening up.

For more than a decade, we have always adhered to the principle of combining social services and legal education services
