Chang'an Avenue (simplified Chinese: 长安街; traditional Chinese: 長安街; pinyin: Cháng'ān Jiē), literally "Eternal Peace Street", is a major thoroughfare in Beijing, China. It is often referred to as the Shili Changjie (simplified Chinese: 十里长街; traditional Chinese: 十里長街; pinyin: Cháng'ān Jiē), meaning the Long Street of Ten Li. Chang'an is the old name for Xi'an which was the capital of China during the Tang Dynasty and other periods.

Strictly speaking, Chang'an Avenue only encompasses West Chang'an Avenue and East Chang'an Avenue. However, it is also used to refer to the stretch from Fuxingmen on the Western 2nd Ring Road to Jianguomen on the Eastern 2nd Ring Road.

In very broad terms, it refers to the stretch of road (the Extended Chang'an Avenue) as the route from Shijingshan District through to Tongzhou District, including portions of the Jingtong Expressway.

This article, and related articles, consider it to be the road from Fuxing Road through to the beginning of the Jingtong Expressway (E. 5th Ring Road). Others have defined it as the road from Shijingshan Road through to Dawangqiao on Jianguo Road.

Chang'an  listen (help·info) (simplified Chinese: 长安; traditional Chinese: 長安; pinyin: Cháng'ān; Wade–Giles: Ch'ang-an) is an ancient capital of more than ten dynasties in Chinese history, today known as Xi'an. Chang'an literally means "Perpetual Peace" in Classical Chinese. During the short-lived Xin Dynasty, the city was renamed "Constant Peace" (Chinese: 常安; pinyin: Cháng'ān); yet after its fall in AD 23, the old name was restored. By the time of the Ming Dynasty, the name was again changed to Xi'an, meaning "Western Peace", which has remained its name to the present day.

Chang'an had been settled since the Neolithic times, during which the Yangshao Culture established in Banpo in the city's suburb. Also in the northern vicinity of the modern Xi'an, the tumulus ruler Qin Shi Huang of Qin Dynasty held his imperial court, and constructed his massive mausoleum guarded by the famed Terracotta Army.

From its capital at Xianyang, the Qin dynasty ruled a larger area than either of the preceding dynasties. The imperial city of Chang'an during the Han Dynasty was located in northwest of today's Xi'an. During the Tang Dynasty, the area to be known as Chang'an included the area inside the Ming Xi'an fortification, plus some small areas to its east and west, and a major part of its southern suburbs. The Tang Chang'an hence, was 8 times the size of the Ming Xi'an, which was reconstructed upon the premise of the former imperial quarter of the Sui and Tang city. During its heyday, Chang'an was one of the largest and most populous cities in the world. Around AD 750, Chang'an was called a "million people's city" in Chinese records, while modern estimates put it at around 800,000–1,000,000 within city walls. According to the census in 742 recorded in the New Book of Tang, 362,921 families with 1,960,188 persons were counted in Jingzhao Fu (京兆府), the metropolitan area including small cities in the vicinity.

John Winston Ono Lennon, MBE (9 October 1940 – 8 December 1980) was an English musician and singer-songwriter who rose to worldwide fame as one of the founder members of The Beatles, one of the most commercially successful and critically acclaimed acts in the history of popular music. Together with Paul McCartney, he formed one of the most celebrated songwriting partnerships of the 20th century.

Born and raised in Liverpool, Lennon became involved as a teenager in the skiffle craze; his first band, The Quarrymen, evolved into The Beatles in 1960. As the group disintegrated towards the end of the decade, Lennon embarked on a solo career that produced the critically acclaimed albums John Lennon/Plastic Ono Band and Imagine, and iconic songs such as "Give Peace a Chance" and "Imagine". After his marriage to Yoko Ono in 1969, he changed his name to John Ono Lennon. Lennon disengaged himself from the music business in 1975 to devote time to raising his infant son Sean, but re-emerged with Ono in 1980 with the new album Double Fantasy. He was murdered three weeks after its release.

Dong Chang (董昌) (d. July 3, 896) was a warlord of the late Chinese dynasty Tang Dynasty. He began his career as the leader of a local militia at Hang Prefecture (杭州, in modern Hangzhou, Zhejiang) and gradually increased in power to control most of modern Zhejiang. Not satisfied with the titles that the Tang emperors bestowed on him, he claimed imperial title in 895 as the emperor of a new state known as Luoping of the Great Yue (大越羅平). His vassal Qian Liu turned against him and killed him, seizing his territory, eventually becoming the founder of a new state of Wuyue.

It is not known when Dong Chang was born, but it was known that he was from Lin'an (臨安, in modern Hangzhou, Zhejiang), which was part of Hang Prefecture (杭州). During the rebellion of the army officer Wang Ying in 876-877, Dong joined a local militia to defend against Wang's raids. After Wang's rebellion was defeated, Dong, for his contributions during the campaign, was made the defender of Shijing Base (石鏡, in modern Hangzhou).
