Hi, Wendy. Yeah, for the TAC cost, Q2 obviously was a very special quarter. I mentioned last time, our momentum – very much the medical-related revenue were affected, and a much of that was organic. And so, you could see that in Q2 it was a very pronounced increase of the TAC rate. In Q3, other than that, we were implementing the measures across the board, and some of the other verticals are also, of course, affected by this. And the TAC ratio was not only because of the medical or organic revenue. And therefore, it kind of fluctuate a bit. Directionally, over time, you should expect the TAC rate to continue to increase as a percent of revenue, simply because we're growing, on one, the mobile contextual related revenue, and much of that is yet to be fully developed. And that generally pays a higher TAC rate. And, if they bring a bigger contribution to the overall revenue, we should expect TAC rate to go up. I think Wendy, for the mobile CPM, obviously it continues to improve, but I think at this moment of time the comparison may not be very meaningful, because much of the changes is going through. PC, obviously, we're changing the display method. And so, there is a lot of other variables that's moving around to affect. But generally, of course, we continue to believe that mobile has tremendous monetization power and would continue to improve its capability and narrow, and eventually we think it's the process of the mobile monetization capability. For SG&A expenses related to O2O, we mentioned earlier that we have continued improvement, or thinking, or revelation in the O2O area. We want to connect people with services, and as we are executing on this business, we're very much focused on the user value proposition, and merchant value proposition. And, of course, at the same time deploy our SG&A investments in a very disciplined manner. Our three-year plan for Nuomi for O2O has not changed. But I think, we're – as I mentioned earlier, we're approaching the business in a very disciplined approach, and a focus on ROI added the value generation to our users and merchants.
