How to translate the line_item.title in order page

if customer purchased an order with CN , the line_item.title will capture the CN title of the product of the line .

once customer access order detail page , it will display CN even in a EN site.

may I know how can i translate the line_item.title in this scenario?

Translating the line_item.title on the order detail page in a Shopify store, especially when dealing with multiple languages, can be a bit complex. The line_item.title property captures the title of the product at the time of purchase, which means it reflects the language that was active when the order was placed. If a customer orders in Chinese (CN), the line_item.title will be in Chinese, even if they later view the order details in an English (EN) version of the site.
