-## 定位
-ushio-session是js-session的前身，内置于[iotcat/ushio-js](https://github.com/iotcat/ushio-js)。在使用[iotcat/fp](https://github.com/iotcat/fp)定位设备的基础上，前端用户可以像使用cookie一样使用session。session不依赖与cookie，使用服务端存储。因为这个特性，**session可以解决cookie所难以解决的跨域问题**。
+## Positioning
+ushio-session is the predecessor of js-session, built in [iotcat/ushio-js](https://github.com/iotcat/ushio-js). On the basis of using [iotcat/fp](https://github.com/iotcat/fp) to locate the device, front-end users can use sessions like cookies. The session does not depend on cookies and uses server-side storage. Because of this feature, **session can solve cross-domain problems that cookies are difficult to solve**.
