Because the pages in the new version doesn't need to be edited (hard-coded), it seems better to use PO/MO directly for the multi-lingual website.
<?php
/**

* This global variable is used to detect the language that the user's browser is using.
* Should be passed to step to get the specified language's MO file.
*/
function applemint_locale( $locale ) {
//Create a global variable so that other functions and hooks can use the variable to determine the language.

According to the original template file, I tried to create another tag that can integrate the TW address field in Contact Form 7.
<?php
add_action( 'wpcf7_init', 'wpcf7_add_address_tag' );
function wpcf7_add_address_tag () {
wp_enqueue_script( 'address-pick', get_template_directory_uri() . '/js/tw-city-selector/dist/tw-city-selector.min.js', array( 'jquery' ), true ) ;
//Get the js file from https://github.com/dennykuo/tw-city-selector
wpcf7_add_form_tag( array( 'address', 'address*' ),
//To-do: 還沒處理必填欄位的功能
'wpcf7_add_address_tag_handler', array( 'name-attr' => true ) );
}
