1. The back office of the Criminal Investigation Brigade needs to assist in handling the daily affairs of the Criminal Investigation Brigade, including document drafting, meeting organization and information transmission. At the same time, it is also necessary to be responsible for file management, financial management, personnel management and other aspects of work. The work is complicated and needs patience and care to complete, so the back office of the Criminal Investigation Brigade is not good.

2. The backstage of the Criminal Investigation Brigade needs to assist the leaders of the Criminal Investigation Brigade to manage and assess the personnel of the Criminal Investigation Brigade, including personnel deployment, training and assessment. These tasks need to bear responsibility and pressure, and they need to have strong organization and coordination ability and adaptability, so the internal strength of the criminal investigation brigade is not good.
