Hello, Wade Yang,
Thank you for choosing XStore as your WooCommerce WordPress theme.
Shipping settings are independent of our theme, we would recommend you read the documentation of the WooComerce plugin https://woocommerce.com/document/setting-up-shipping-zones/ and contact their support https://wordpress.org/support/plugin/woocommerce/
We hope this information is helpful.
Kind Regards, 8theme team
