Routing did not work properly in laravel 5.1

I am currently doing a project called Doctor Management System.In this project I am stuck because my route did not work correctly.Whenevr I have to go on a specific id it gives me Gibberish id. My Route file is

Route::get('/district/hospital/hospital_info/{id}', array('as' =>'hospital_info' ,'uses' => 'UserController@hospital_info'));

My Controller is

    <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;
use App\Division;
use App\District;
use App\Category;
use App\Dcategory;
use App\Hospital;
use App\Doctor;
class UserController extends Controller
{


        public function hospital_info($id)
        {
            $divisions = Division::all();
             $division=Division::find($id); 

             $district=District::find($id); 
             $category=Category::find($id);
             $hospital=Hospital::find($id);


            return view('users.hospital_info')
                        ->with('divisions',  $divisions)
                        ->with('division', $division)
                        ->with('district', $district)
                        ->with('category',$category)
                        ->with('hospital',$hospital);
        }

My view file is

<?php $active="hospital"; ?>
@extends('layouts.dashboard')
@section('content') 

    <section id="blog" class="container">
        <div class="center">
            <h2>Hospital Information</h2>
