 So, yeah, we can start here, I see more people are browsing in here. So, Mr Lee, come over here to me. Then let's start today, right? So, Open Tech Summit 2019 in Shenzhen. Yes, we're here. Welcome. I think the story begins from last year. This is the second year we organized Open Tech Summit in China. Absolutely, and yeah, we know that it's always a bit challenging to start. We had this story last year, so Mr Lee is worried. So many people signed up, but where are they in the morning? So we know it's challenging sometimes to find the place and so on. But it's not a problem, and I think we just have people browsing in. You guys come down here, join us. So, I think it doesn't stop us from actually getting into the topic. And I think we have already seen a lot of interesting people joining us here. A lot of tech knowledge already here. I see tech talks and so on. So, what is the program of today? And what can we do? We'll go through a few slides with you guys. And yeah, so we have the Open Tech Summit here. This is the QR code, by the way, for WeChat. I know WeChat is not a free and open source, but it's the main messenger here in China. So, yeah, I mean, we have to somehow communicate with each other and with everyone. So this is the solution we do in China. As you know, it's sometimes difficult to use other solutions. So we use these solutions for anyone who has questions about the messenger, which is not open source, but maybe we can talk with the tech center here. They're also based in China in the future. Yeah, let's go step by step. So, yeah, Wei Xin, right? So maybe I just also want to remind you we will move to another place in the afternoon that we will have more workshops this time and maybe even more tomorrow. So we will move into another place, Open Fiesta. And so this year we're going to do something different and maybe we encourage everybody to communicate with each other and I hope you will enjoy the event. And maybe I will also represent the Tsinghua English City and also Open Fiesta to welcome all the participants, our speakers from all over the world. Thank you for joining us. Yeah, so Mr. Li, we can also like have a little bit of detail here about the program as you just mentioned. So, yeah, let's have a look. So come over with me here and let's do this together. So we have different tracks here. So the registration is open here at the moment when we move the registration to the Open Fiesta building. Open Fiesta, what does it stand for? And then fiesta, because I know some Spanish people say yes, let's have fiesta. Fiesta means party in Spanish. So, but what does it actually stand for here in China? Yes, actually, it's an acronym. It's Open Factive for Innovation, Science, Education, Technology and Art. It's kind of like the, we are quite interested in this institute and it will try to do the innovative ways to educate students. So it's really a pleasure to collaborate with Fosigia and Tech Summit again. So we can come back to the schedule. But, yeah, so what's the plan? So yesterday we had a tour already at Huachang Bay and then we had an AI meetup at our friends' home, Huachang Bay. And then in the evening we had a nice dinner. It was wonderful. I think it was Xinjiang food. So it's always really nice to also experience the local culture. China has so many cultures, so it's really a pleasure. So who was there, by the way, at Huachang Bay Tour? Is anyone here? Yeah? Okay, they're behind. Yes, I remember. It was really fun, right? Yeah. Cool. And so today we start in the morning in the main track and then we move in the afternoon. And there we have our friend from MySQL with talks. Our friend from Red Hat will give workshops and AI and systems. We call it under this umbrella covering different topics. And of course we have hardware makers and we have a workshop on open source video. It's always good to be practical and how to do things, right? So we have two areas, which is really deep tech. And then we also have areas for people who want to know how to use open source software in a practical way. The plan is for the evening that we have a social dinner. That will also be here in the canteen in the Mensa. But the nice thing here in Xinjiang is the Mensa. It's not like a Mensa that some people know in Europe, right? It's like food that we don't always want to eat. We have very nice Mensa. So if you guys join us, that would be really nice. And it's really great food. And tomorrow, Mr. Li, what's the plan? So we have a Python workshop with Rabbi Li. And then we also have OpenXLab. What is the OpenXLab? I think OpenXLab is something we try to do. We try to explore with you. So we're really welcome for you to bring your project to explore with us. And also we have some project from the post-Asia community, like PSDA, like SUSE AI. And maybe I think you will introduce that a little bit later. Yes, I will definitely introduce that. But I think we could also use this as a call to the participants here. So what we'll have when we have a big space, and in this space we have different tables. And at these tables, people can showcase their projects, but they can also sit down just like in a high-space university or conference kind of mixture. And if you have any open-source project that you would also do like to showcase there, that's your chance. We have some tables reserved for the community. So it's not just a small table. It's a really nice big table where like eight people can sit around at a laser. And China is always like so flexible. We can always fit more people as well. So that's not really the problem. So if you have any project that you would like to collaborate with and possibly new people, please join us at the open access. Yeah, so I think that's pretty much the overview. And of course, like it's really we should go here and then into the summit organizers, right? I mean, you already mentioned, so false data. If you guys don't know false data, please come to me or come to Mr. Witte. We're back here in the front. We're all one of the developers. And yeah, we also have a few people joining us over the event from the post-ageal community. And of course, we are here at Tsinghua University. So Tsinghua is originally from Beijing? Yes, but we have actually a children's conference that started many years ago. And now we are shifting in from this Tsinghua University children's international training school and we have a longer plans to make it a global campus and maybe the future half-student or international students. So we already heard a bit about the concept of open fiesta. And now, of course, we should thank our partners for the event you already mentioned, the Susiai and Fiesta. But we also have the support of CQ work together with them. Continuously, who are they? CQ is quite famous open source hardware providers in Shenzhen. And they also now they focus more on IoT, like IoT solutions. And also we have Open Eye, which is like open source, like AI community, like just started in Pongchang Land. And we are quite honored to be part, collaborate with them. And of course, we have the open source project. We will mention that later. Okay. Good. So here is the QR code again for the channel. If you miss it now, you know, pass it off like ask your neighbor, ask other people to get you in the channel. It's a, which a channel so we can communicate with each other and you can answer questions to each other. So Open Tech Summit 2019. So, Gili, I give the words to you to talk a little bit about more about Open Fiesta or... Yes, I think we're running a little bit late. I think we will, because we will go to Open Fiesta. So we will explore Open Fiesta more in the afternoon and probably tomorrow. So maybe I will leave the stage tomorrow to have the first stage.
