In 2021, the company's revenue was 3.356 billion yuan, and its gross profit was 456 million yuan. Among them, the revenue from other businesses was 390 million yuan, and the gross profit was 340 million yuan. The company contributed 75% of the profit with this part of revenue, which accounted for 12%. Is this part of the revenue basically for waste material processing? Is it sustainable? Is it a normal phenomenon in the industry?

Changying Credit: Hello, investors. The 390 million yuan of other business income is mainly from scrap business income. As the company's business scale continues to grow, the scale of this part of scrap income will increase accordingly, and the accounting caliber will remain consistent. Thank you!
