For many foreigners who have visited or worked in China, one of their strong impressions is that the country is very safe. Here , you can go out alone late at night to eat at a food stand without feeling nervous. You can also let your younger children ride public transport all by themselves without worrying about their safety.

This year, 2018 , marks 8 special anniversary of the launching of the reform and opening up policy, which took place two score years ago in China. Over the past few decades, the country has achieved fast economic growth, while social peace and stability have been maintained(维护) to the fullest extent at the lowest cost. Of course, there are still unsolved problems. However, from the overall aspect, Chinese society remains harmonious and safe. In my eyes , this should be attributed(归于) largely to the cultural ;economic and political environment of the country.

A society can be stable and orderly only when its people can lead a prosperous(繁荣的) life. After the introduction of the reform and opening up policy, China achieved fast economic growth and significant scientific and technological progress. In the meantime, the Chinese government has taken various measures such 2s those to fight corruption, reduce poverty and promote the rule of law, in order to uphold social equity. Thanks to these efforts, the potential factors that might cause social problems have been greatly reduced.

Apart from government departments including the police and judicial(司法的) departments , the general public also contributes much to social governance. The development of information technology has created new ways of linking the police and the public. By jointly fighting crimes in such ways, the public and the police have developed an ever-increasing level of mutual trust and positive interaction.

The safety and stability in China did not come easily. Rather; it should be attributed to the efforts made by 1.3 ‘billion people. For both Chinese and foreigners living in the country, the sense of safety and security is very precious.
