What is your understanding and opinion on new energy vehicle sales?

New energy vehicles, the biggest pain point is the battery, although there are several more advanced technologies, such as Tesla's power management technology, rapid charging and power exchange in China, but the most fundamental facilities require huge investment, of course, including the major manufacturers of technological updates and development. In the future, if we can have more perfect power management technology, popularized charging or power exchange facilities, and reasonable price, I believe it can bring endless development space for new energy vehicles. In addition, if we can solve the various shortcomings of various power generation and battery end-of-life problems, perhaps we can look at the development of new energy vehicles from another perspective.
