How to write in UrlManager rules?

Question

Yii

I have such a link, here instead of city1=11 and city2=1 the name of the cities should come out, not the id of the city. I want to configure via urlmanager rules, but I don't know how, can you help?

'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'rules' => [
                'o_nas'=>'site/about',

            ],
        ],

Pass SLUG instead of ID. And you will be happy. And in URLManager regular expressions. Read about yii2 slug and you will understand how it's done. The task is typical and popular. For example How to implement slug in yii2?
