So the city of Shenzhen is actually the first city in the world to achieve a full electric bus and taxi fleet. So that means 16,000 buses and 23,000 taxis. So as you can imagine, that's a really big transition to make happen. And this, of course, is driven largely by policymakers that we have and trying to advance the industry of the electrical vehicle. And behind this political will there is a lot of collaboration between different departments in in a municipality, for example, land use for building charging stations and charging poles and the traffic control to give priority to the electrical vehicles. And also, of course, financing plays a big part as well. However, not to overlook there's the innovation in the private sector and finance sector also play a really key role in actually making it happen. As you can imagine, transitioning from a diesel vehicle to an electrical vehicle, it's actually really costly. So for example, one electric bus costs about 1.8 million RMB, which is a lot of money, and they have to have a lot of them. So there was a lot of national and city level subsidy to make it happen, which really took a lot of pressure away, but in the end it's still a lot of money, a lot of pressure for the bus companies. So the private sector the finance institutes come together, and then they offer this scheme that basically the financier to buy these buses and rent them out to bus companies to help them to achieve this transition.
