一个查询结果是json，但其中的汉字变成了unicode

Question

前几天刚刚开始学习php，还没有入门，所以遇到的问题都很基础。

我连接mongodb查询：

<?php
header('Content-Type:application/json; charset=utf-8');

// 省略了connect to mongodb

$filter = ['number' => '23097155-1'];

$options = [
    'projection' => ['dqyl' => 0],
    //'sort' => ['zxbh' => -1],
];
$query = new MongoDB\Driver\Query($filter, $options);
$cursor = $manager->executeQuery('table', $query);
foreach ($cursor as $document) {
    $results[]=$document;
}
$jsonData=json_encode($results);

   echo $jsonData;

?>

结果返回了json,但其中的汉字都变成了unicode：

[
    {
        "_id": {
            "$oid": "651612b17399f4534ad78a1d"
        },
        "alias": "db_virtual_library",
        "type": {

        "bz": "\u7532\u73ed",

    }
]

怎么处理下呢？

我希望查询出这样的：

[
    {
        "_id": {
            "$oid": "651612b17399f4534ad78a1d"
