Zonheng Design: Currently, the income from projects related to "low-altitude economy" and "commercial spaceflight" accounts for a very small proportion of the company's consolidated income.

Zhongheng Design released an announcement of changes. According to the company's disclosed "Annual Report for 2024", the company was awarded some design projects for new productive industries such as low-altitude economy and commercial aerospace. However, due to limited individual project design contract amounts, the design revenue from projects related to "low-altitude economy" and "commercial aerospace" currently accounts for a small proportion of the company's consolidated financial statements.
