Sure. In terms of the category, we're very diversified. We try to -- not to have concentration of the risk in our business. So from five-star, four-star, three-star and also hostel, as we discussed before, the revenue is very evenly spread. No segment will -- we will not concentrate on one segment. That is why, no matter what happened in the market, our model is very resilient. Secondly, we do not normally take inventory risk. We only, you know, the most of the customers we have guaranteed allotment, so, unless it's really during the peak, peak season for one or two hotels that you need to buy. But most of the hotels we just need to have a guaranteed allotment to -- with the hotels to ensure the availability. And based on our volume, hotels will prioritize Ctrip's customers in order to get a great volume from us. So in that, the booking and accounting is similar to the commission rated hotels. In terms of the contribution into the future, I think Ctrip started with the business travelers, and we're very aggressive moving into the travel -- leisure travel business. So for our team, have hired people in the second-tier cities, third-tier cities to make sure all this inventory reflected in our platform on a timely manner. And in addition, not only we have our own self-contracted team, we also opened it to the market. So to an extent, in a market, there are other players with better inventory availability, we'd be happy to lift their inventory onto our platforms as well. That is why our growth rate in the past few quarters have demonstrated very strong growth, although our base is very large, our growth rate has been pinned at around 69% for last quarter. I think the concerted efforts into the pricing and coverage are the main reason contributing to our strong growth.
