Hi @MichaelTsai and welcome to the Seller Community! This is currently a feature request and unfortunately there isn't a way to have more than one language setting for your online store. I can see how this feature could benefit our sellers and I will send the feedback to our Development team. Thank you!
At the moment having multiple languages is not a feature of Square Online store, however you can create multiple websites now - you could build a new website for each language you wanted to support. Other than that I don't have a workaround, however will pass your feedback on as a feature request.
@wangjueliang they would - though you could set up a home page at the main URL with links to the other sites, so that all traffic can flow through the same original domain if you have a specific URL you want to use to direct customers to your website(s)!
There isn't currently a way to do that outside of creating individual sites for each language, @dumplingnation. However, I'm merging your post into a feature request thread about this so you can get easily updated if that changes.
@AlinaVH I've taken a look and unfortunately this doesn't seem possible at the moment. Though I can see how that option would save you a lot of additional work in this scenario!
I'll forward your feedback to our eCommerce team, unfortunately I don't have an elegant workaround to suggest in the meantime!
