【正文】 better satisfy on Chines users needs by all kinds of offerings from Baidu.How much of you total Ramp。D now is going towards mobile versus test out so if you talk a little bit about the shift specifically in Ramp。D spending in how that spending you wear that spending is going from desktop to mobile and then we should expect mobile to bee a material business and I guess material could mean anything if you percent 10 percent. But we talking you know one year three years five years have how far are you looking.Right now, about 25 percent of we resources are devoted to mobile and that number is subject to change, that could change next month, could change next quart, or could change next year, because the market is changing. So we have constantly reevaluate on resource allocation but right now the numbers about 25 percent, of course,the revenue from mobile is much less than that. And although it’s growing very fast as them mentioned in the beginning of the talk, the revenue at least tripled this year,but it’s still a single digital contribution to the total revenue. Exactly when it will became more material, revenue source I don’t not, in no harry to figure that out because we know that there are a lot of room for improvement for the mobile CPM, so we will continue to work on that we are, like mentioned, we are developing an infrastructure to support a lot of mobile app developer which them can run their apps on our services. We hope to figure out the business model later on, from that yet. But that’s probably at least a three year time line for any revenue or profit.What the question about your core business on you’ve got a new challenge from Archie who 360 recently and I’am just wondering on that on the desktop search, at this point is innovation slow down its gonna be easier for petitors to catch up to you and what are you doing to innovate for their in and expand your lead.I’ve been working on the search engine for many many of years, and I firmly believe whoever could provide the best user experience will be able to win the market for search. Search is a very petitive matter, you have to develop a lot of Ramp。D resources and be very focus in order to e up the best search quality. We have hugely over, almost the all of the petitor in terms of our a search quality and we will continue to develop more resources especially the Ramp。D resources into the Chinese search. So we believe in a longer term, users will still e to the best quality search engine wherever that is in China elsewhere, it’s just some time search distribution China could mand a small percent of search traffic but that’s not bee a really peting product to me. I think you can find distribution China here and there, but it’s at the end of the day the search quality that well that will drive most of the Internet users to a search engine.Thank you. Sorta following up on that same question is there anything different about 360 versus the other petitor that you’ve previous faced,you know successful in the market and secondly from that you know how do you think about the runway remaining in you know core desktop search,obvious the growth opportunity there.I think there petitors that focused on search quality, and there are on sometimes petitor sometimes partners that focus on China or distribution, for example, the tele carriers was a important distribution in China for our search, and some of them still are, they have their value in the value chain, sometimes we choose to work with them, sometimes them choose to someone else and pete with us, I think that’s OK, as end of a game, if we provide the best user experience, we will be able to win the market, I think time is up.Would you take one more question?OK, one more.So my name is Iwiki.He’s got a attacked at any time stuff..Yeah, I’m from school of education. So love to talk about the business and technical issues. So I’m wondering like how do you see the social value created by Baidu in China and also what kind of social impact want to make in the future.We took a different approach from many of the US kind parsing in terms of social, back in 2003 we launched a product called “貼吧”, post bar, it’s probably the first what web product before the term web with client in the , it represents more than 10 percent of our total traffic and tens of millions of users log on to enjoyed on this online munity or in today’s terms social, the way it works that whenever you typing a query, not only we show you a list of web search results, we also show you a bar that allow people who typing thinkable to exchange ideals, that’s a very popular product in China. After that, we also launched the Baidu Knows, Baidu *** and quite few other social products, so today the traffic for Baidu social product actually surpassed the traffic for web search. So we have a very strong social product right now as just again, what’s the right business model for social?In the past the social products for Baidu was really defined to help you search to better find information to stay on Baidu, to use our web search more. But going forward, there might be a good model for this social products to just make money by themself. We are studying that, we are also hopeful because our social products are generally interestbased,its relatively easier to deliver as spacebased user’s interest rather than demographic information. So we think our social products is a more valuable than the typical social networks in other panies.
