Thank you, Karl. This is Steven. I'll take your question. As the media has already widely reported lockdown situation in China, and realistically is difficult for us from a supply chain and manufacturing perspective to really forecast what's going to happen next. And in that environment and context, it's nearly impossible to really plan on a going forward basis. Having said that, because the COVID-19 situation has been ongoing for the past two to three years. We have already made sufficient contingency plans, including moving part of the operations to the U.S. And potentially, as we mentioned in our prepared remarks, opening factories in the U.S. to essentially alleviate this situation in the future. In terms of the short-term effects, I think unfortunately, we just have to deal with not just the lockdown in specific cities, but also the supply chain being massively disrupted. And these are completely out of control. Take for example, when we fulfill a certain order, our upstream suppliers are facing the same issues in terms of manufacturing, gathering of raw material, having sufficient workers in the factories and resolving logistics issues. So in a nutshell, it's not just what we can or we cannot control, essentially, we also cannot control our upstream suppliers. In that context, we will do our best to diversify our solutions, including the above-mentioned moving into North America and we are also seeking other solutions. The [Indiscernible] for the projection of revenue, I think in that backdrop, is almost impossible to project what we're going to do for the whole year. But on a quarter-to-quarter basis, we're still largely positive, because we believe that we are transitioning well into the new business, as evidenced by the fourth quarter. And even though I can't really provide any guidance, but we think that as we move towards Q1, Q2, we should more or less be able to come up with a steadily improving and growing business, presenting that to the market. Thank you.
