Reply To: I have 2 questions, please teach me..

Hello,

I saw the screenshot you attached.

1) The tabs are controlled by a woocommerce plugin and our theme doesn’t influence them.

You can read the woocommerce documentation in the following link:
https://docs.woocommerce.com/document/editing-product-data-tabs/

2) You can change the text using the loco translate plugin and your path will be Loco Translate >> Plugins >> Woocommerce.

Screenshot for Clarification: https://prnt.sc/ztw1tr
