How to enhance the ability and responsibility of entry-exit administration agencies and relevant departments to discover cross-border illegal and criminal activities?

Excuse me, how to enhance the ability and responsibility of immigration authorities and relevant departments to find cross-border illegal and criminal activities? The ways to enhance the ability and responsibility of entry-exit administrative agencies and relevant departments to discover cross-border illegal and criminal activities are as follows:

1. Concentrate on the pursuit of important suspects who are at large for crimes that hinder the management of national (border) territory, resolutely pursue the leaders, behind-the-scenes organizers, transporters and key elements of fugitive gangs, and severely punish them according to law.

2. Severely crack down on "illegal immigrants" in border areas, dynamically control key personnel and places, severely crack down on "black motorcycles", "black taxis", "black ferries" and "black guides" that provide reception, transit and hiding for illegal immigrants, and severely crack down on the backbone of gangs that occupy border areas and illegal employment in the black market, so as to prevent illegal immigration activities from bringing into the epidemic.

3. Focus on cracking down on illegal and criminal activities that destroy border facilities. Severely punish illegal acts such as deliberately destroying border facilities, digging underground holes, opening tunnels indiscriminately, and building pontoons on rivers privately, so as to prevent the weak points of epidemic prevention and control from being formed due to the destruction and weakening of blocking facilities.
