I think first of all, we have a view that actually from the fact also that this new national standard will be very - actually strictly enforced. But, having said that, it basically - it trickles down, I mean, it takes time to actually get to what is called a tier 4, tier 5, tier 6 cities. If you look at top tier cities, like tier 1, tier 2 basically, Beijing, Shanghai, Guangzhou, Shenzhen, and also the provincial capitals, almost from day-one, April 15, right, on day-one that's already in place. Now, I mean, just to - as I mentioned in the call, it's basically enforced on the manufacturer level, basically from our level, and in scooters we shipped out has been what is called a 3C, basically get a 3C certificate from the China CQC Center. They are people checking the - local enforcement are checking on the retailers on way to weekly basis, to make sure the retailers doesn't sell anything that is non-compliant. And lastly - and just want to make it then for like City of Beijing, right. What you see is actually, there are policemen on the street, are chasing people who don't have a license plate for their scooters. And then, if you don't have a license plate with scooters, at this point, it's only RMB 20 fine. But I think there is also announcement within a few months or so that that fine will actually get to about RMB 1,000. So we do see the - it is as we expected that this regulation is being strictly enforced.
