 一个微型的Arcaea本地服务器  A small local server for Arcaea
 
 ## 简介 Introduction
-这是基于Python以及Flask的微型本地Arcaea服务器，可以模拟游戏的主要功能，一时兴起在五天之内糊了出来。这可能是我第一次写这种大程序，若有不妥之处，敬请谅解。  
-This is a small local Arcaea server based on Python and Flask, which can simulate the main functions of the game. I completed it on the spur of the moment in five days. This may be the first time I have written such a large program. Please understand if there is something wrong with it.
