There are a variety of factors triggering incidents in public locations. Their negative impact is the last thing we can underestimate. The alcohol-related violence disrupts public order and may cause irreversible physical and mental damage to victims. Illegal gatherings and protests present a serious challenge to the social safety and stability. Moreover, a flood of crimes in public areas also constitute a huge threat to the society.

　　Net cafes, bars and railway stations are the crime-torn places, so more police must be dispatched to these priority areas. A series of crime prevention measures must be taken to guarantee public safety, especially in these crime-prone areas. Let's make the public places crime-free through our long-term unremitting efforts.

　　When a variety of problems plague the information systems, the critical importance of information security becomes the focus of people's concern. It does deserve the unprecedented emphasis. It is widely accepted that information security, to some extent, outweighs other spheres in the field of information. So the related authorities, enterprises,
institutions and organizations place the high priority on it.

　　Information Security concerns a range of problems- information interception, loss, damage etc. Business and military information leakage will have an devastating impact. For the information owners and monitors, they must drive their efforts to enhance the security protection and maintenance. For example, a strict control over the access to the secret data shouldn't be absent. The network and software provider should take a set of tailored protection measures targeting different computer crimes. The security issues should be also considered at the legislative level, so we are clamoring for a law designed to clamp down on various cyber crimes.
