A well-established and reputable large property management company in Shenzhen was impersonated by multiple illegal companies. Under the property management's entrustment, lawyers Wang Tengfeng and Sun Shujie conducted extensive evidence collection across various locations, proving that some companies engaged in illegal or even criminal activities, severely infringing on the property company's legitimate rights and interests and disrupting the national economic order. Through the efforts of the representing lawyers, the property management company not only recovered substantial economic losses but also saw some suspected criminals undergoing further processing by judicial authorities.
