Not sure what your question is. Maybe try to be a little bit more specific next time...

If you want to change the currency of your Shopify store, click on "Settings" in the bottom left corner. Then, in the "Store Details" page change your currency in the "Store currency" section.

We has a order test 1 order, so we can't change option.

If it's only a test order, just delete it. If that's not an option, you will need to contact shopify support here to change your currency: https://help.shopify.com/en/questions
