In the investigation of the South China Sea bubble incident, the Congressional Secret Committee appointed Charles snell to audit the accounts of the South China Sea. This is the first time in the history of Congress to entrust a private third-party independent accountant to conduct an audit investigation. As a result, Nanhai Company was successfully found to have serious fraud and false accounting.
