Laravel translation not working

问题

<?php
return [
    'welcome' => 'Welcome',
    'mail' => 'E-Mail address',
    'password' => 'Password'

I am referencing the keys either using @lang() or {{ trans('') }}. Example:

<label for="email" class="col-md-4 control-label">{{ trans('admin.login.mail') }}</label>

However this gets returned as:

When you're putting language files into subfolder, you need to specify it using slash. So, try this instead:

{{ trans('admin/login.mail') }}
