    foreach ($sheng['son'] as $shi){
        echo '| - | -  '.$shi['area_id'].'-'.$shi['area_pid'].'-'.$shi['area_name'].'-'.$shi['lng'].'-'.$shi['lat'].'<br />';
        foreach ($shi['son'] as $qu){
            echo '| - | - | -  '.$qu['area_id'].'-'.$qu['area_pid'].'-'.$qu['area_name'].'-'.$qu['lng'].'-'.$qu['lat'].'<br />';
