Secretary Dong, hello! Tonight, a business partner said that 95% of high-precision maps used to be repaired by manpower, but now they use LD maps (lane-level navigation maps), 99% of which are generated by large models, and 1% is improved by manpower. LD maps can open one city in one day. 1. What proportion of the company's lane-level navigation maps can be generated by AI? How much cost reduction compared to before? 2. What is the company's current speed of opening cities with lane-level navigation? How many cities have lane-level navigation been opened so far? Thank you!

NavInfo: Hello, the company is actively trying out the latest AI algorithm innovations and exploring the automation of various elements of high-precision maps in many scenarios. The efficiency is continuously improving. The company's lane-level navigation products are being launched one after another and will gradually cover urban areas across the country from 24 years. Thank you for your attention.
