Thank you. I'll take the first question then. If I understood you correctly, it's about our digital solutions, right? So really at the heart of our digital platform is the doctor-patient interaction platform. And in addition to that we also digitally track the drug flow from factory to patients. In the past, a lot of those transactions actually happening in offline. And the other capability we have built out over the last few years is really digital marketing, which we have seen an tremendous progress and of course our smart sourcing greatly helping those pharmacies when they place orders. In the past, they use a sheet of paper and they figure out what SKUs they need to replenish, and then they will spend half a day to call different suppliers. With our digital tool, which is called the digital -- our smart sourcing, they can complete their procurement within, let's say, five minutes instead of half a day. And of course, and I think one thing we've done the best in the industry is really the Patient Care Program. I'll just give you some examples, right. So with the Patient Care Program, we have a D plus one, D plus seven, T minus seven and T minus 10. Let me just quickly go through that. For instance, what is DB, so let's say diagnosis. On the first day when the patient got diagnosed and I'm assuming this is a chronical patient, obviously a drug is prescribed and delivered, and of course our platform will be able to use different algorithm based on different DB types And on day one, after the diagnosis, we're going to send out a material related to the disease, the education material. And the D7, we're going to send out the importance of following on the compliance over the doctor's prescription and so on. And T means the time they should be refilling. So T minus, our system is going to automatically calculate. We're going to send out a note to the patient to remind he or her, him or her, it's about time to refill. And by T minus zero, on the actual day, if it is still not happening, obviously our pharmacists can follow up with the call and then try to find out what's going on. And the other thing we are very proud of is really the digital marketing we are conducting for pharmaceutical companies, and especially when it comes to patient education, the doctors' education, the pharmacist education. And essentially we have built out a -- I don't know how to describe this in English, it's . It's a matrix of different high traffic media. For instance in China, the biggest traffic came from Doyin, from Toutiao, from WeChat and so on. So we all -- we as a company set up accounts in all those big traffic sites and when we run a patient education program, we can actually reach much, much broader audience and compared to a single pharmaceutical company can do. We'll give you an example. We conducted a diabetic education, sponsored by Eli Lilly and during the live session, we had more than 5 million users participate and then we actually recorded in that session, overall over 10 million people actually viewed that session. That is a clear advantage over the traditional ways with the digital solution we have and obviously we're going to really exploit that capability we have. I don't know who should follow-up the next question.
