Answer the question at the end by quoting:

Fairport Convention are a British folk rock band. Formed in 1967, they are widely regarded as a key group in the English folk rock movement. Their seminal album Liege & Lief is considered to have launched the British folk rock movement, which provided a distinctively English identity to rock music and helped awaken much wider interest in traditional music in general. The band have drawn heavily on the Child Ballads, songs of the British Isles from the later medieval period until the 19th century.
The new band began a hectic schedule of performing in Britain and the World and prepared material for a new album. The result was the all-instrumental Expletive Delighted! (1986). This showcased the virtuosity of Sanders and Allcock, but perhaps inevitably was not popular with all fans. This was followed by the recording In Real Time: Live '87 which managed to capture the energy and power of the new Fairport on stage, despite the fact that it was recorded in the studio with audience reactions dubbed on.  In this period the band were playing to larger and larger audiences, both on tour and at Cropredy, and it was very productive in terms of recording. Fairport had the considerable composing and arranging skills of Allcock and, to fill the gap created by a lack of a songwriter in the band, they turned to some of the most talented available in the contemporary folk scene. The results were Red & Gold (1989) The Five Seasons (1990) and Jewel in the Crown (1995), the last of which was judged 'their bestselling and undoubtedly finest album in years.'  At this point, with Mattacks busy with other projects, the band shifted to an acoustic format for touring and released the unplugged Old, New, Borrow Blue as 'Fairport Acoustic Convention' in 1996. For a while the four-piece acoustic line-up ran in parallel with the electric format. When Allcock left the band, he was replaced by Chris Leslie on vocals, mandolin and fiddle, who formerly worked with Swarbrick in Whippersnapper, and had a one-off stint with the band replacing Ric Sanders for 1992 Cropredy Festival. This meant that for the first time since reforming, the band had a recognized songwriter who contributed significantly to the band's output on the next album Who Knows Where the Time Goes (1997), particularly the rousing 'John Gaudie'. By the time of the 1997 thirty-year anniversary Festival at Cropredy, the new Fairport had been in existence for over a decade and contributed a significant chapter to the history of the band.

IN: Yen was born in Guangzhou, China. His mother, Bow-sim Mark, is a Fu Style Wudangquan (internal martial arts) and Tai Chi grandmaster, while his father, Klyster Yen (Zhen Yun Long ), is a newspaper editor. When he was two years old, his family moved to Hong Kong and then to Boston when he was 11. His younger sister, Chris Yen, is also a martial artist and actress, and appeared in the 2007 film Adventures of Johnny Tao: Rock Around the Dragon.

Yen describes himself as a mixed martial artist. He learned Tai Chi from a young age under his mother's tutelage. He then wanted to learn Taekwondo in his teenage years, earning a 6th Dan in the process. At the time, the Beijing Wushu Team had a scout in the United States and invited Yen over to Beijing, China, where he began training at the Beijing Sports Institute, the same facility where champion-turned-actor Jet Li trained; this is where the two of them crossed paths for the first time.  Upon his return to the United States, Yen won gold medals in various wushu competitions.  Yen later went on to discover and seek knowledge on other martial arts styles; he would later obtain black and purple belts from judo and Brazilian Jiu-Jitsu, respectively, and went on to study the art of Parkour, Wrestling, Muay Thai, Kickboxing and Boxing under various trainers. His exposure to mixed martial arts (MMA) was heightened when he went back to the United States from 2000 to 2003. While making his Hollywood debut, he also took time off to learn the various martial arts forms. Yen's progress was evident when he returned to Asia, where he implemented his newfound knowledge of MMA, showcased in films such as SPL: Sha Po Lang (2005), Flash Point (2007), and Special ID (2013).  Near the end of 2007, Yen added a new martial arts system to his arsenal. He was offered the role of Wing Chun grandmaster and mentor of film star Bruce Lee, Ip Man, in a 2008 film named after the grandmaster. He worked hard and studied Wing Chun under Ip Man's eldest son, Ip Chun, for 9 months before tackling the role. Ip Chun has since praised Yen for his effort, his skills as a martial artist, and his ability to grasp the full concept of Wing Chun much faster than anyone else he has taught.  Yen believes that combining many martial arts together will produce the most effective and harmonious style. Yen has said, "When you watch my films, you're feeling my heart." He believes in practical combat, and in his opinion, MMA is the most authentic type of practical combat. He has mentioned that he would have competed in the Ultimate Fighting Championship if he did not have a recurring shoulder injury.

how long did he train there?
