To set the store language on Shopee Thailand, you first need to log in to the merchant backend and find the "Settings" option.

In the settings, select "Language Settings" or similar options to enter the language selection page.

On this page, you can select Thai or other supported languages ​​as the default language of the store as needed.

After the settings are completed, save and exit, and you can see that the store interface has been changed to the selected language. To ensure customer experience, it is recommended to provide an English option at the same time to facilitate international buyers to browse.
