I read your company's 2022 annual report, and found that among the divisional products, there is an item called "other businesses". The gross profit margin was not disclosed separately later. I calculated that the gross profit margin is 73%. What does this other business do? Is this other business consistent with the other businesses reported from 2014 to this year?

CATL: Dear investors, other business income mainly includes waste and material sales income, technology licensing income, and R&D service income. In general, other businesses are related to the company's main business, are sustainable, and are also a reflection of the company's technological capabilities. Thank you for your attention.
