Over the past year, through continuous interactions with you, we have collected a large number of practical questions raised by everyone during pre and post-purchase process of our miners, and also gained a clearer understanding of your core needs. The establishment of the knowledge base is mainly to answer various basic questions for you in a targeted manner before and after miner purchase, and meanwhile popularize product basic knowledge and relevant training content to help you understand our products more comprehensively and in-depth. In addition, we hope to further increase interactions with you in the new year and collect more real questions. We will continuously improve the content of the knowledge base and provide more tailored solutions based on your needs, and we also welcome you to share your questions with us.
