echo trans('validation.required'):

Default locale is ‘en’ in ‘config/app.php’ file of ‘fallback_locale’ ! What you want to change is ‘locale’ by yourself !

Edit ‘locale’ in ‘config/app.php’ to ‘zh_cn’ , create floder ‘zh_cn’ in ‘resources/lang’ , then add one file named ‘commom.php’ widthin content :

return [
    'Home' => '首页',
    'Login' => '登录',
    'Register' => '注册',
