The impairment recognized on intangible assets were RMB412, nil and RMB41,563 (US$5,943) for the years ended December 31, 2023, 2024 and 2025, respectively. Amortization expense of intangible assets for the years ended December 31, 2023, 2024 and 2025 were RMB7,420, RMB29,413 and RMB135,785 (US$19,417), respectively. The increase in amortization expense and impairment loss for the year ended December 31, 2025 were primarily due to the rapid evolution of AI and robotics technologies in the industry, which shortened the expected period of use and reduced the expected future economic benefits of certain technology-related intangible assets. The revision of estimated useful lives was accounted for as a change in accounting estimate on a prospective basis in accordance with ASC 250. As the affected intangible assets have been fully amortized or impaired, there is no impact on amortization expense in future periods.

Estimated amortization expense relating to the existing intangible assets with finite lives for each of next five years and thereafter is as follows:
