<human>: Background: Michelle Wingshan Kwan (born July 7, 1980) is a retired American figure skater. She is a two-time Olympic medalist (1998 and 2002), a five-time World champion (1996, 1998, 2000, 2001, and 2003) and a nine-time U.S. champion (1996, 1998-2005). She is tied with Maribel Vinson for the all-time National Championship record. She competed at the senior level for over a decade and is the most decorated figure skater in U.S. history.
Context: Michelle began to develop a more mature style in 1996. Her new, more artistically expressive programs were "Romanza" (short program) and "Salome" (free skate). She also improved her extension, speed and jump technique, and performed to more difficult choreography. She won both the U.S. Championships and the World Championships in 1996. In the later event, she edged out defending champion Chen Lu in a very close competition in which both competitors garnered two perfect 6.0s for Presentation in the free skate.  In the 1996-97 season, Kwan skated to "Dream of Desdemona" (short program) and "Taj Mahal" (free skate). During this season, Kwan struggled with her jumps because of a growth spurt and problems with new skating boots which she wore for an endorsement contract with the manufacturer. She fell twice and stumbled once in her free skate at 1997 U.S. Nationals, losing the title to Tara Lipinski. She lost the Champion Series Final to Lipinski a month later. At the World Championships, Kwan stepped out of her triple lutz combination and placed 4th in the Short Program portion of the competition behind Lipinski, France's Vanessa Gusmeroli, and Russia's Maria Butyrskaya. Kwan skated a six triple, mistake-free performance to win the freestyle portion of the competition, but placed second to Lipinski overall.  Kwan started out the 1997-1998 Olympic season by winning Skate America (where she defeated Tara Lipinski) and then Skate Canada. However, she suffered a stress fracture on her foot and was forced to withdraw from her third Champions Series Final. Kwan regained her U.S. title from Lipinski at the 1998 National Championships, despite her fractured toe. Many people consider her performances of her Rachmaninoff short program and free skate set to William Alwyn's "Lyra Angelica" at the 1998 U.S. Championships to be the high point of her career from both a technical and artistic standpoint. The performances earned her fifteen perfect 6.0s and left one judge in tears.  Kwan and Lipinski were co-favorites to win the 1998 Olympic Games in Nagano, Japan. Kwan placed first in the Short Program portion of the competition, winning eight first place votes out of nine judges. In the free skate, Kwan skated a clean 7-triple performance but placed behind Lipinski, who also did 7 triples including a triple loop/triple loop combination and a triple toe-loop/half-loop/Triple Salchow. Kwan ended up winning the silver medal, with the gold medal going to Tara Lipinski and the bronze medal to Chen Lu.  Lipinski and Chen both retired from competitive skating shortly after the Olympics, while Kwan went on to win the 1998 World Championships in Minneapolis. CANNOTANSWER
