 We actually live in two worlds, of course we live in the physical world but knowing it or not we also live in the virtual world, right? We go to social media, we go to online movies and so far these two worlds are largely divided. There is a gap between them. Now, to be sure there's talk in business and technology that's known as all to all or online to offline. The meaning there is what you do online can actually benefit what you do offline. So for example, if you shop for something online then that thing can be delivered to you. Now what we envision in the future is not only online to offline but online with offline. Together they define who you are, they define what you do. What you do online and what you do offline can be totally transparent. You live in this combined and integrated world. Now of course to make this true, we need a lot of technologies that can follow you and can make sense of your physical activities. Examples are things like this and mobile phones and so on. So these devices by Moore's law are coming down very, very quickly in prices. But really to make it really happen we need something much deeper and that something much deeper can link the meanings between the two worlds. What you do online, what does it mean by taking this action over this merchandise and what you do offline, how do you link these two activities together. Now in fact we have the technology that's known as artificial intelligence to make this true. Now so artificial intelligence we can think of it as a tool, it's just a more advanced tool such as this which consists of a lot of processors that are linked together but it has the ability to learn from the activities online and activities offline and can make this connection so that from the photos it sees it can understand the meaning, oh it's looking at a cat, it's looking at a human face. And when we put these two worlds together and let artificial intelligence do the linking we can automatically discover a number of what we know as bridges between the two. So the two worlds can be truly and smoothly integrated. Now in fact we have done a number of experiments in seeing how these different worlds can be connected. For example when you play chess you think about strategies which can benefit your business activities and in our experiment that actually happened. When you look at a picture this is a beautiful picture of Hong Kong University of Science Technology, maybe some poetry come to your mind and indeed we made this tool. This is a Chinese poetry that automatically generated from this picture. So this is yet another example. But can we make actual use to that to impact our everyday life? Here's yet another experiment in which we attach some sensors to birds in order to get a good sense of bird flu, how the bird flu migrates along with the birds when they travel between continents. But the problem with that is the sensors we can attach to these birds are very few so the data is very difficult to understand. But don't worry when we combine that with a virtual world for example social media spots on people's spotting of bird flu and reports of sickness we can get a much better sense of the bird flu traveling behavior. And we have other technologies that can group people together find communities that can even enhance that kind of understanding much much better. So eventually we can not only take that technology to link different worlds in parallel but also link different worlds from the past to the future. So what we do in the past the black and white picture can benefit what we do in the future so people's knowledge is accumulated over time. And so by means of artificial intelligence and the big data technology when we truly integrate the virtual and physical world it's just like the beautiful reflections in this picture the reflections and the physical parts are in one world and fully integrated. Thank you very much.
