Back to the 1960's,China, the whole nation was suck into a disorder situation,and laws especially the constitute gave way to red guards movements. As Zheng Nian, a author who was famous for her memoir Life And Death in Shanghai, described in the book,laws at that time were Mao's words.Since three decades have past, the Chinese people get rid of the shadow of that dark time, and laws are again the weapon for ordinary people when they are attacked.I agree with the claim that people should obey the just law and resist to the unfair for laws is a public affair which are  strategies of constraining people and  need the concentration of every person in the society.

Just laws refer to those rules that can guarantee the society as a normally running machine. Consider the conception of society in the 17th century, scholars described the formation of a society or a nation as give and take game: People take away some of their rights and live in a corporate way and instead, the community has to protect their life and properties. Based on such conception, just laws should do no harm to the life of the participants of the society. Unjust laws however, is the oppsite, the one that can do harm to people in a society.What the most important is, however, people were not indifference about the unjust treatment. So many peole,attoneies or judgers were dedicated to maintain the justice of laws bacause it relats to the entire society, and no one can be a bystander.

Consider the first amendment of the America Constitute. It was first set to protect citizen's lieberty of speech and there is no wonder that everyone will feel pleased about that.However, during the next 200 hundrud years, this amendment faced test so many times. During the early years of the 20st century, people would be arrested if they made speech about the commusism. What the most important is, however, people were not indifference about the unjust treatment. So many peole,attoneies or judgers were dedicated to maintain the justice of laws bacause it relats to the entire society, and no one can be a bystander.
As to the resistance to the unreasonable or unjust laws, I believe that there are always some people  wise enough to see the danger. When talked about the demolition in Chinese metroploities, Chinese writer, Yan Lianke, said in his article 2011,The Year of strary dog published in the New York Times in April,2012, when people realized they are facing unjust treatment, they will seek ways to express their disatisfication and to arise the public attention to destroy the unjust. A similat case is in an Arab country,Egypt. When concluding the success of their revolution over the old dictators, the  jounalist of Cario said the youth in Egypt expressed their desire in the Internet with the help of social website, Facebook or Twitter. Their emotion drew attention of people in other places which offered them help to break the old and unreasonable system.
Also, sometimes the distinction of justice and unjustice might not be clear: Probably the just law for the business takers is  not just at all to those hard workers. Laws, however, are improved step by step,and this are motivated by the social progress. The way to realize such progress, which is demonstrated in the history of most contries, is to miantain the just laws and revise or even dischard the unjust.
