right now zencart show user's address in this wany

address,
address,
state
country
Firstname Lastname ****

however, in China, we prefer to switch the first/last name, in the different order

Lastname Firstname ****
address,
address,
state
country

how???

I found these code in file such as
inlcudes/templates/template_default/templates/tpl_create_account_success_default.php

<?php echo zen_address_format($addresses['format_id'], $addresses['address'], true, ' ', '<br />'); ?>

so, where is $addresses['address'] generated?
