I would like to ask if the company has carried out corresponding hedging operations for copper, the main raw material, to ensure the stability of raw material costs?

Xinzhi Group: Hello investors, thank you for your attention. Since the beginning of this year (especially in the second quarter), I believe that all companies involved in copper-related materials have felt the rapid rise in copper prices, and the company has been under great pressure; since 2020, the company has been making some changes in sunshine procurement and other aspects, and has done some linkage work for price fluctuations in upstream and downstream. Thank you!
