The China League One (aka Chinese Jia League) is the second tier professional league for Chinese football clubs. The league is under the auspices of the Chinese Football Association. Above the League One is Chinese Super League.

Prior to the formation of Chinese Super League, Jia League was known as Jia B League. The then top two levels of Chinese football league were known as Jia A League and Jia B League respectively. Jia A was rebranded as CSL and Jia B was rebranded as the current Jia League in 2004. Below the Jia League is the Yi League, following the Chinese Heavenly Stems naming convention of numbers.

It is currently made up of 16 teams, playing each other home and away once. At the end of each season, the top two teams will be promoted to CSL and the two lowest placed teams from CSL will be relegated to the China League One. The top two teams from China League Two will be promoted and replace two lowest placed teams from China League One.

China (ⁱ/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.

The People's Republic of China is a single-party state governed by the Communist Party of China. It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). Its capital city is Beijing. The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.

Football League One (often referred to as League One for short or Npower League 1 for sponsorship reasons) is the second-highest division of The Football League and third-highest division overall in the English football league system.

Football League One was introduced for the 2004–05 season. It was previously known as the Football League Second Division and prior to the advent of the Premier League, the Football League Third Division.

There are 24 clubs in Football League One. Each club plays every other club twice (once at home and once away). Three points are awarded for a win, one for a draw and zero for a loss. At the end of the season a table of the final League standings is determined, based on the following criteria in this order: points obtained, goal difference, goals scored, an aggregate of the results between two or more clubs (ranked using the previous three criteria) and, finally, a series of one or more play-off matches.

At the end of each season the top two clubs, together with the winner of the play-offs between the clubs which finished in 3rd–6th position, are promoted to Football League Championship and are replaced by the three clubs that finished at the bottom of that division.

Datuk Lee Chong Wei (simplified Chinese: 李宗伟; traditional Chinese: 李宗偉; pinyin: Lǐ Zōngwěi; born October 21, 1982 in Georgetown, Penang) is a professional badminton player from Malaysia who resides in Bukit Mertajam. Lee won the silver medal in the 2008 Olympic Games, thus becoming the first Malaysian to reach the final of the men's singles event and ending Malaysia's Olympic medal drought since the 1996 Games. This achievement also earned him the title Datuk, and a description by Malaysian Prime Minister Najib Tun Razak as a national hero.

As a singles player, Lee was ranked first worldwide on August 21, 2008. He is the third Malaysian men's singles shuttler after Rashid Sidek and Roslin Hashim to achieve such a ranking (since official rankings were first kept in the 1980s), and is the only Malaysian shuttler to hold the ranking for more than two weeks.

Lee is one of the most accomplished Malaysian badminton players having won two All-England championships. However, he is still searching for his first Olympic Games, World Championship and Asian Games titles as the world number 1.
