If your store language is in either Traditional Chinese, Simplified Chinese, or English, HK Pickup Options can be configured for these languages.
Make sure you set the language that HK Pickup Options should be displayed in by going to HK Pickup Options > Settings > Languages.
You are able to configure the option titles, descriptions, as well as shipping methods (if you are on the advanced plan) in language that you have set.
If your store is using Langify or Weglot translation apps to set multi-language on your storefront, you can configure HK Pickup options to support multi-language alongside these apps as well. Learn more here.
