As someone not familiar with Toutiao, could you describe how the Q&A function works from a user perspective?

I'm guessing there's a part of the app where the user goes for Q&As. If a user asks "How do I flush my car's cooling system?", does the question get sent to all users who like cars?

Once a question is submitted, the AI engine automatically recommends a list of relevant experts/potential answerers to the questioner to choose from. As a user you can choose who you want answers from. In addition the system also pushes the question to relevant users based on their interest graph. The system then also sorts the recommended answers based on its quality.
