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.
QUESTION: when did he start martial arts?
IN: Ahmad Shah Durrani (c. 1722 - 16 October 1772) (Pashto: Hmd shh drny), also known as Ahmad Khan Abdali (Hmd khn bdly), was the founder of the Durrani Empire and is regarded as the founder of the modern state of Afghanistan. He began his career by enlisting as a young soldier in the military of the Afsharid kingdom and quickly rose to become a commander of the Abdali Regiment, a cavalry of four thousand Abdali Pashtun soldiers. After the assassination of Nader Shah Afshar in 1747, Ahmad Shah Durrani was chosen as King of Afghanistan.

Durrani was born in or about 1722 to Mohammad Zaman Khan, chief of the Abdali tribe and Governor of Herat, and Zarghuna Alakozai. There has been some debate about Durrani's exact place of birth. Most believe that he was born in Herat, Afghanistan. He was born as Ahmed Khan. Abdali's father suffered "Persian captivity for many years" at Kirman before being released from prison in 1715. As a refugee, he "made his way to India" and joined his kinsmen at Multan. After he raised his family there, he was recognized as the "scion of hereditary Sadozai chiefs". It is believed that Zaman Khan returned to Afghanistan to fight the Persians and his Afghan rivals, but left one of his wives at Multan because she was "in the family way". So other sources believe that, Abdali was born at Multan in 1722, after which she returned to Afghanistan to reunite with her husband. He lost his father during his infancy.  Durrani's forefathers were Sadozais but his mother was from the Alakozai tribe. In June 1729, the Abdali forces under Zulfiqar had surrendered to Nader Shah Afshar, the rising new ruler of Persia. However, they soon began a rebellion and took over Herat as well as Mashad. In July 1730, he defeated Ibrahim Khan, a military commander and brother of Nader Shah. This prompted Nader Shah to retake Mashad and also intervene in the power struggle of Harat. By July 1731, Zulfiqar returned to his capital Farah where he had been serving as the governor since 1726. A year later Nadir's brother Ibrahim Khan took control of Farah. During this time Zulfiqar and the young Durrani fled to Kandahar where they took refuge with the Ghiljis. They were later made political prisoners by Hussain Hotak, the Ghilji ruler of the Kandahar region.  Nader Shah had been enlisting the Abdalis in his army since around 1729. After conquering Kandahar in 1738, Durrani and his brother Zulfiqar were freed and provided with leading careers in Nader Shah's administration. Zulfiqar was made Governor of Mazandaran while Durrani remained working as Nader Shah's personal attendant. The Ghiljis, who are originally from the territories east of the Kandahar region, were expelled from Kandahar in order to resettle the Abdalis along with some Qizilbash and other Persians.  Durrani proved himself in Nader Shah's service and was promoted from a personal attendant (yasawal) to command the Abdali Regiment, a cavalry of four thousand soldiers and officers. The Abdali Regiment was part of Nader Shah's military during his invasion of the Mughal Empire in 1738.  Popular history has it that the Shah could see the talent in his young commander. Later on, according to Pashtun legend, it is said that in Delhi Nader Shah summoned Durrani, and said, "Come forward Ahmad Abdali. Remember Ahmad Khan Abdali, that after me the Kingship will pass on to you. Nader Shah recruited him because of his "impressive personality and valour" also because of his "loyalty to the Persian monarch".
