Wordpress，save_post，post_status并不是数据库中的功能

Question

add_action("save_post", [$this, "save"]);

function save($postId)
{
    $post = get_post($post_id);
    echo $post->post_status; // its "inherit" instead of "publish" !
    echo $post->post_status; // its "revision" instead of "draft" !
}

然后在数据库中有“ publish”，我得到get_post($post_id)->post_status =>'inherit'！

或数据库中有“ draft”，我得到get_post($post_id)->post_status =>'revision'！

为什么？我需要根据post_status进行一些操作，但我不能那样做
