Next-generation products gradually replaced old products after large-scale production, reducing costs; at the same time, the company strengthened communication and negotiations with suppliers to reduce the procurement prices of the main raw materials, IC chips, IGBTs, capacitors, etc. in the procurement process, which combined to increase gross margin; the gross margin level in 2024 is expected to remain the same as in 2023.
