Okay. , I will take your first question regarding the margin, and second question, regarding the fulfillment, logistics cost. And for the first question, our strategy towards healthy business model has been working very well. And we are seeing significant improvement on both our product margin, as well as services margin. And there are couple of initiatives going on these two areas. Firstly, as Junling just mentioned, we are reducing our procurement costs. from pharmaceutical companies has been highly effective in lowering our product cost. Currently, we direct source from over 550 global and domestic pharmaceutical companies and we will continue to deepen our strategic relationship with these partners, as well as we will secure new partnerships. Such relationships provide us with a wide range of product at much lower cost. And the second level, we can further improve the margin is through optimization of product assortment and structure. Currently, we are at annual sales revenue of over RMB10 billion and with our over 400,000 pharmacies in our B2B platform, we are in a position to balance our portfolio of products low margin products, which by together with very healthy margin for us. And we have now about 5,000 SKUs with very good margin, including our private label products and those new products of pharmaceutical companies. And we are very confident that we will be able to help our pharmaceutical partners in commercializing their products with high efficiency and high margin. On the services revenue and services margin part, our digital platform provides a comprehensive solution for pharmaceutical companies by integrating doctors, pharmacists, medical assistance, patients and medical representatives onto our Internet hospital. The service module also provides online remote consultation and provide e-prescription, patient-to-patient and also patient support, and refill services. And these features enable us to provide customized omni-channel digital marketing solutions for our pharmaceutical partners. The market continues to show strong demand for our diverse portfolio of services solutions. We are seeing a 70% year-over-year growth on our services revenue, which helped 111 to improve our overall profit. And for your second question regarding the logistics cost, yes, it's a very good catch. Yes, there is a minor increase on our fulfillment cost in this quarter to 3.2% of total revenue. And in last year, we have increased our budget on logistics network to better serve our customers, including, we expand our warehouse space to support the business volume growth, but as we just mentioned during the pandemic, our business growth slowed down because of the lockdown, etcetera. So, percentage of revenue follows fixed fulfillment cost like warehouse increased. On the other hand, because of the lockdown and traffic control in Shanghai and many other cities in China, traditional logistics network was sometimes suspended. And some of these network is even suspended until today. So, we have to use much more expensive way as interim solution, which also creates additional cost on our in-bound and outbound logistics.
