所以我想从model和controller返回一些字符串，但它总是说undefined变量，尽管当我用dd($a)和dd($b)检查它时，它成功通过了。我做错了什么？
about.blade:

@extends('layout.template');
@section('homeContainer');

<p> {{ $a }} </p>
<br>
<p>{{ $b }}</p>
@endsection

AboutController :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\AboutModel;

class AboutController extends Controller
{
    //
    public static function info(){
        $a = AboutModel::info();
        $b = "This data is from controller";
    

        return view('about', compact('a', 'b'));
    }
}

AboutModel :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class AboutModel extends Model
{
    use HasFactory;
    
    public static function Info(){
        $a = "This value is from model";
        return $a;
    }
}

Routes :

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\AboutController;

/*

Route::get('/', function () {
    return view('welcome');
});


Route::get('/about', function () {
    return view('about', [
        "name" => AboutController::info(),
    ]);
});
