Question: How many years after the Hanshi Festival's creation did it take for the Qingming Festival to be created? Passage 1:Gooch earned her BS in Computer Engineering in 1996 and her MS in Computer Science in 1998 from the University of Utah. While working on her master's degree, she explored interactive non-photorealistic technical illustration as a new rendering paradigm and developed Gooch shading, which she presented at the 1998 SIGGRAPH conference. Following her masters, she worked at the University of Utah as a research scientist for five years. During this time, she co-taught a course at the 1999 SIGGRAPH conference on non-photorealistic rendering and co-authored the first textbook in the field, Non-Photorealistic Rendering, with her husband Bruce Gooch. In 2004, she began her PhD in computer science at Northwestern University and graduated in 2006. Following her PhD, she joined the faculty at the University of Victoria in British Columbia as an assistant professor of computer science. In 2013, she joined the Scientific Computing and Imaging Institute to help develop the ViSUS software core into a product. In 2014, she became an adjunct professor of computer science at Texas A&M University.
 Passage 2:The festival originated from the Cold Food or Hanshi Festival which remembered Jie Zitui, a nobleman of the state of Jin (modern Shanxi) during the Spring and Autumn Period. Amid the Li Ji Unrest, he followed his master Prince Chong'er in 655 to exile among the Di tribes and around China. Supposedly, he once even cut meat from his own thigh to provide his lord with soup. In 636, Duke Mu of Qin invaded Jin and enthroned Chong'er as its duke, where he was generous in rewarding those who had helped him in his time of need. Owing either to his own high-mindedness or to the duke's neglect, however, Jie was long passed over. He finally retired to the forest around Mount Mian with his elderly mother. The duke went to the forest in but could not find them. He then ordered his men to set fire to the forest in order to force Jie out. When Jie and his mother were killed instead, the duke was overcome with remorse and erected a temple in his honor. The people of Shanxi subsequently revered Jie as an immortal and avoided lighting fires for as long as a month in the depths of winter, a practice so injurious to children and the elderly that the area's rulers unsuccessfully attempted to ban it for centuries. A compromise finally developed where it was restricted to 3 days around the Qingming solar term in mid-spring.
 Passage 3:The Honda Civic tour was the biggest production the band had had so far. The stage was constructed of 3 ramps up to a platform behind the drum set, and 6 large video screens behind that. The show began with a large black curtain concealing the stage while the band played an instrumental intro, with spotlights revealing the silhouettes of the band. As the intro ended, they begin playing "Ignorance" as the curtain simultaneously dropped, the video screens flashing the band's logo during the intro, as the intro progressed the video screen changed to images of light bulbs (similar to the song's music video) during the intro, light bulbs also swung down from the top of the stage, continuing to swing throughout the song. The band then played "Feeling Sorry" as the video screens each showed a live feed of each member of the band performing during the choruses, at the end of the bridge the band would stop playing and Hayley would greet the crowd and welcome them to the tour. After playing "That's What You Get" and "Emergency" the band played "Playing God" as the video screens showed images of picture frames, the same picture frames on the back of Brand New Eyes and the song's single cover. After that they played Careful, as images of the Brand New Eyes butterfly flashed during the chorus, they then continued with their hit-single "Decode" as the video screen showed the band running through the forest with fireworks and flares, the video has been described as a part-two to the songs music video. After that Hayley Williams and Josh Farro moved to stage left and performed an acoustic cover of Loretta Lynn's "You Ain't Women Enough." After that, a red couch (similar to the one on the cover of All We Know is Falling) and a small lamp were brought out and the band performed a three song acoustic set, during this the light bulbs from Ignorance were brought down again to illuminate the stage. After that the band returned with "Let the Flames Begin" while the video screens showed images of open hands during the 'Oh Father' outro. They then performed "Crushcrushcrush" and "Pressure " stopping in the bridge during "Pressure" for Hayley to introduce all the band members, and for Josh to introduce Hayley. They then performed "Looking Up" while each of the video screens showed lyrics to the song and each of the band members daily lives, at the end of the song all the members came together to ride bikes as the split-screens faded away. They then ended their main set with their biggest hit "The Only Exception" as pyrotechnics were used during the last chorus of the song. The band then exited and come back for an encore, starting with "Brick By Boring Brick" while the video screens showed various images, including deserts, snakes, the Brand New Eyes butterfly, and hot air balloons. After "Brick" the band concluded their set with their breakthrough song "Misery Business" as flashing images of the "Riot!" logo filled the video screens, during the bridge Williams would let one, or sometimes various fans on stage to sing the rest of the song or sometimes play guitar, and as the last chorus came in confetti cannons were shot towards the crowd. The set concluded with the video screen showing Paramore's logo and the band bowing then leaving the stage. They used the same production for their Oceania and UK tours.
