It's the 15th year of ChinaJoy, China's biggest digital entertainment expo. All kinds of nerd stuff here. For video games, Ubisoft, CD Projekt Red and Mojang are among the big foreign names making an appearance, along with dozens, if not hundreds, of local companies. For anime and comics, there're cosplay shows, dance competitions, and like a million people in impractical outfits. Expect photographers, marketing people, nerds, geeks, pretty expo ladies (in order of decreasing density). Tickets are available at the ChinaJoy website. Starts 9am every morning, goes till about 4pm.
