1.先下载中文版wps，将对应版本下的mui目录 拷贝出来备用

D:\wps\WPS Office\11.2.0.9528\office6\mui

2.卸载中文版wps，下载新的国际版wps，并将之前备份的mui文件下的所有文件复制进来（选择覆盖）

D:\wps\WPS Office\11.2.0.9281\office6\mui

3.向mui\lang_list\lang_list.json这个json文件添加内容，注意格式和文件尾部的逗号

{
        "locale" : "zh_CN",
        "online" : false,
        "plugin_name" : "lang_zh",
        "type" : "",
        "text" : {
            "name_zh" : "中文",
