-        "Redux is a state management framework that can be used with a number of different web technologies, including React.",
-        "In Redux, there is a single state object that's responsible for the entire state of your application. This means if you had a React app with ten components, and each component had its own local state, the entire state of your app would be defined by a single state object housed in the Redux <code>store</code>. This is the first important principle to understand when learning Redux: the Redux store is the single source of truth when it comes to application state.",
-        "This also means that any time any piece of your app wants to update state, it <strong>must</strong> do so through the Redux store. The unidirectional data flow makes it easier to track state management in your app.",
-        "<hr>",
-        "The Redux <code>store</code> is an object which holds and manages application <code>state</code>. There is a method called <code>createStore()</code> on the Redux object, which you use to create the Redux <code>store</code>. This method takes a <code>reducer</code> function as a required argument. The <code>reducer</code> function is covered in a later challenge, and is already defined for you in the code editor. It simply takes <code>state</code> as an argument and returns <code>state</code>.",
-        "Declare a <code>store</code> variable and assign it to the <code>createStore()</code> method, passing in the <code>reducer</code> as an argument.",
-        "<strong>Note:</strong>&nbsp;The code in the editor uses ES6 default argument syntax to initialize this state to hold a value of <code>5</code>. If you're not familiar with default arguments, you can refer to the <a target=\"_blank\" href=\"http://beta.freecodecamp.com/en/challenges/es6/set-default-parameters-for-your-functions\">ES6 section in the Beta Curriculum</a> which covers this topic."

+        "在Redux中，有一个状态对象负责应用程序的整个状态， 这意味着如果你有一个包含十个组件且每个组件都有自己的本地状态的React项目，那么这个项目的整个状态将通过Redux <code> store </ code>被定义为单个状态对象， 这是学习Redux时要理解的第一个重要原则：Redux存储是应用程序状态的唯一真实来源",
+        "这也意味着，如果你的应用程序想要更新状态，只能通过Redux store执行，单向数据流可以更轻松地对应用程序中的状态进行监测管理",
+
+        "“Redux <code> store </ code>是一个保存和管理应用程序状态的<code> state </ code>，你可以Redux对象中的<code> createStore() </ code>来创建一个 redux <code> store </ code>. 此方法将<code> reducer </ code>函数作为必需参数，<code> reducer </ code>函数将在后面的挑战中介绍,该函数已在代码编辑器中为您定义。它只需将<code> state </ code>作为参数并返回一个<code> state </ code>即可",
+        "声明一个<code> store </ code>变量并把它分配给<code> createStore() </ code>方法，然后把<code> reducer </ code>作为一个参数传入即可",
+        "<strong>注意:</strong>&nbsp;编辑器中的代码使用ES6默认参数语法初始化此状态以保存<code> 5 </ code>的值. 如果你不熟悉默认参数，,你可以参考<a target=\"_blank\" href=\"http://beta.freecodecamp.com/en/challenges/es6/set-default-parameters-for-your-functions\"> ES6课程</a>，它里面涵盖了这个内容"
