Are data labeling and data training for autonomous driving different business concepts? Can the company's autonomous driving simulation test be considered data training? Does the simulation test currently generate revenue? Thank you!

NavInfo: Hello, the main directions of our company's simulation business are: 1. Simulating driving environment to verify whether the trained self-driving model has the ability to cope with certain scenarios; 2. Providing some training data that is difficult to collect in the simulated real environment to help the training model deal with corner cases; 3. Providing error correction/improvement guidance for the self-driving function R&D stage by evaluating and outputting intermediate data during the operation process. Thank you for your attention.
