The company's sales of lightweight parts in 2021 dropped significantly, and its overseas revenue also dropped. What is the specific reason? Is it because of the decline in general orders? Will growth resume this year? Thank you

Bethel: Dear investors: Hello! The company's revenue from lightweight parts in 2022 increased by nearly 30% year-on-year. With the commissioning of lightweight parts production capacity in the Mexican company and the mass production of lightweight parts products in overseas markets, the company's revenue from lightweight parts will continue to grow. Thank you for your attention!
