"Li" represents the practical manifestation of the harmonious and just principles underlying "li"-based systems. From this perspective, technology can help people overcome physical and age-related limitations, enabling them to better participate in social and economic activities. This embodies humanity's efforts to implement the concept of "li" through technological progress. In this case, Suzhou-based Plus Technology has been exploring autonomous driving technology for years, aiming to free people from repetitive, tedious and unsafe jobs. By enabling more efficient and safer production methods, this technology advances social equity and harmony.
