Thank you. I think let me take the questions. So we really enjoyed the growth in the last 3 years. It's really the S2B2C model that's propelling the growth. For any business to sustain this level of growth, we've got to have a model to propel that growth. So secondly, it's really the execution of the model. For instance, we started the S2B2C business in the middle of 2017 from 0. We made it a strategic imperative to take on more than 50% of all pharmacies across China. And within 3 years, we're serving more than 300,000 pharmacies. Of course, it's one thing to formulate a strategy, and it's another to execute the strategy. 111 is very proud of its capability and execution. Because of the above 2 factors mentioned, I think we're very confident in sustaining a high-growth rate in future years. And obviously, we had such a wonderful market. It will be a long time before we can reach the ceiling of the industry. The new revenue streams, really, obviously, we already have a fantastic revenue stream. But we have very innovative models by building that supply platform. We should expect not only revenue streams, but also profit streams or margin streams. And we're going to extract more margins out of our e-commerce, the traditional e commerce, as everybody else does, that's easily understood. And of course, we want to create a lot of service modules where we can receive fees. For instance, we have a business model or a business unit internally called JBP, or and if you translate it into English, it's called the treasure box, where we attract a lot of -- little distributors on our platform, and we charge them a fee for providing logistical services and marketing services for them. And of course, we also can build revenue streams out of commercialization for pharmaceutical companies. And there's also digital services and marketing fees, et cetera. So your last question about the B2B's representation in our revenue and the differences with other distributors and so on. It's a very interesting one. I want to approach your question from this angle. If you look at a traditional distributor, it is just a one big B, we are talking about Sinopharm or Shanghai Pharma or et cetera, right. And there are many limitations for one big B in servicing customers in today's digital world. And obviously, 111, is a technology company, and our focus is to build a supply platform to enable small Bs on our platform as well. So we can actually service consumers collectively. I want to give you an example to better illustrate our differences. I spoke about the treasure box or the in our internal organization. So in that business unit, if you look at what we do is that we allow those commercial distributors to put their inventory into our fulfillment centers and they manage their own stock -- in-stock rate, out-of-stock rate and also they manage their own prices. And once an order is placed, we aggregate that order and deliver to the customer in 1 package. So we have thousands of those partners on our platform. So before this particular distributor, he or she can only service the pharmacists in the local city. And now they suddenly have access to over 300,000 pharmacies across the country. Even if it is a single item, we can also deliver in 1 package with minimum marginal cost. But let's also look at the impact on the pharmacy side. Before, they have to work with a few dozens of those distributors. And now they can simply place 1 order on our app and everything will be delivered in 1 order. So instead of a dozen orders, they just need to handle 1 order. And think about the moment when they receive the package, just 1 instead of many. Every order they have to go through quite a number of steps administratively to be compliant according to the regulations here in China. So not only do we help the distributors, the pharmacies, the customers or the consumers, we also create tremendous value for the industry. And think about how much shipping costs we can save over time. So the traditional distributors are not really doing business the way we do. Thank you, I hope that answered your question.
