Okay, let me take all the questions and welcome Tim to comment and add additional inputs. I think for the PDD deal. In my opinion, I would say that’s more like a one off things. Because if you trill down and double-click on the vacation, it is not really apple-to-apple comparison. And because a lot of the details happened to be the, business confidential, not much I can talk about it. But from a very high level point of view, each of the tender, if you breakdown and double-click on that, there’s a CapEx portion. And there’s the OpEx portion and really depends on what you want, and you get a different kind of a pricing schema. And so that you can really compare that was the previous order, or the following orders or tenders, to certain degree. And so that’s one thing. The second thing is most of us know Kindle is the one of the largest e-commerce providers. And then so when they having the project like that, all of a sudden, a lot of the IDC providers, including VNET, were showing interest to win such a local customers. But again, each of the, partners, including VNET, we do have our internal gauge system, to see whether it makes sense and make no sense, and so forth. Sometime you might just give some of the favorable discount to win the local customer is the very first deal; kind of sweeten the deal to win the first one in order to get in. But again, we have to weigh in all the factors. For us, it is not a strategic, deal that we have to win. But again, the question is, will that trigger the price well movie forward? And I would say, I will be very, very honest to say from all the customer calls and customer discussions, it is not, it is more confined into a one-off thing. We have Jiangsu projects, we have other projects in Shanghai, in Beijing in Guangzhou, and also even Northern China. We're not seeing that get with a spread out. That's the answer to your questions. Tim, do you want to take on the second one?
