同样我们再看中国历史上的游牧民族居住的帐篷，之所以长久不变，是因为这是最最适合游牧民族生产作业的建筑功能形式，他们定期或不定期的放牧造成了住所和生产工具的流动性，在经常性的、不断迁徙情况下，帐篷这一简单有效的居住形式因其便于折叠收藏及运输，自然就成了其几千年来不变的居住建筑唯一选择。

But traditionally,once impasses are occured among the people,especially those who both are obstinate and stubborn, therefore, it is no point for the middleman to interpose in, whereas you have to face the situation that you need to suffer aperiodic wrangle though both of them know that they are suffering the severe diseases, i do not want to see something that one of them makes himself or herself lost control or negative consequences will be created due to the wrangle,you know, you cannot realize that you will do some ultra behaviors during the process.

其实针对这点我是看不过眼，或许换着了别的细路，可能早就跳出去或者成家立业了，不要再管他们，但是一定程度上，作为家庭之中的一员，我还是承认自己有权利维护这一切的，在我成长历程里面，尽管他们已没有了那份为工作而奔波的热情，但那份无微不至照顾我的精神我还是看得出来的，有些东西不是讲不讲回报的问题，而是你有无这份心，有无对这些表现感化的问题，因为这毕竟牵涉到你的心灵，你的道德观念。

It reckons that citizens political participation should not be restricted to periodic vote or aperiodic activities such as demonstrations. Citizens should, under the premise of open and transparent information and according to certain procedures, freely and equally carry out in full the discussion on the public policies that affect them, and through the legalization of decision by public deliberation, the quality of democratic governance is enhanced.

协商民主就是在反省竞争性民主理论的基础上，重新赋予公民参与公共事务的积极性，认为公民的政治参与不应该局限于定期的投票和不定期的游行示威等活动方式，公民应该在信息公开透明的条件下，依据一定的程序，自由而平等地对影响到自己的公共政策进行公开且充分的讨论，通过公共协商赋予决策的合法性，从而提升民主治理的品质。
