 I'm here with Yong Li at the Beijing LLVision Technology booth. Hi, Yong. Can you tell us a little bit about what I'm looking at here? It's our smart glass. The smart glass is powered by the display technology of OLED on silicon. The optical system is based on free-form delta-operator plastic. It's made of optical plastic, so it's very small and light and easy to produce. It has 21 degrees of field-of-view and the airbox is about four millimeters. This is our smart glass. It's the lightest one in the world. The weight is only 30 grams, and this is the host of our product. The host is powered by the Intel industrial computing. It's a 100-gigabyte-flows AR processing. So, this is all. Thank you. Can you tell a little bit about this? Are you commercializing this or is this a product now? It's already a product now. We sell it in China for about two months. What is the biggest differentiation you see in this? I see we divided it for professionals. The design ideas of our smart glass influence the extraordinary capabilities of RAI. So, the fit detection and some remote expert can introduce you to how to do what to do sometimes. Okay, great. Thank you for showcasing your technology. Thank you, sir.
