Yes, I know, it's very interesting, Chris, because we have, as you know, a very large employee base over there. I don't know what this count is now, but probably over 400 employees. And we don't, to our knowledge, we've not had a single employee get COVID, of course, we're here in the US, the rest may be 60% of the population is contracted COVID. So they have really adhered to pretty strict program over there that as soon as an individual test positive, they get isolated. And it's common for them to isolate the town in the region if they have a bit of an outbreak. So it's a challenge, if you think about our, we may have suppliers that are in a region that is under quarantine for a period of time, so it's slowing down the delivery of materials that we need. Also for workers be they our workers or workers of our suppliers. If there's an outbreak in your apartment complex, you're quarantine for two to four weeks, they don't leave the complex. So it's fairly, I would say draconian relative to the rest of the world. I guess it's been effective if your goal is to have zero COVID infections, well within our employee base, they've achieved that, but you do it at some cost, which is slowing and interruptions within the economy. So it's something that is a challenge for us. Our employees so far have done a great job in finding alternative suppliers. And working around and through this, trying to stay ahead of our material needs from an inventory management standpoint. But, it's just so uncertain, you just don't know where and if an outbreak is going to occur, and how that might impact you going forward. So it's probably one of our biggest uncertainties I would say around the world right now is the China COVID policy.
