Baotou (simplified Chinese: 包头; traditional Chinese: 包頭; pinyin: Bāotóu, Mongolian: Buɣutu) is a mid-sized industrial city in the Inner Mongolia Autonomous Region of the People's Republic of China. Governed as a prefecture-level city, its urban areas are home to a population of approximately 1.78 million, with a total population of over 2.65 million accounting for counties under its jurisdiction. The city's Mongolian name means "place with deer", and an alternate name in Chinese is "Lùchéng" (鹿城), meaning "Deer City".

Baotou is divided into 10 county-level divisions, including 7 districts,1 county and 2 banners.

The area now known as Baotou was inhabited since ancient times by nomads, most notably the Mongols. Near the end of the Han Dynasty, Lü Bu, a particularly noteworthy warrior, was born here. Compared to the capital, Hohhot, Baotou's construction as a city came relatively late, being incorporated as a town in 1809. The city's site was chosen because it was in an arable region of the Yellow River's Great Bend.

Li Jing (李靖, pinyin: Lǐ Jìng) (571 – July 2, 649), né Yaoshi (藥師/药师, pinyin: Yàoshī), formally Duke Jingwu of Wei (衛景武公), was a general and one time chancellor of the Chinese Tang Dynasty. In 630, Li Jing defeated the Eastern Tujue (Göktürk) Jiali Khan Ashina Duobi with just 3,000 cavalry soldiers in a surprise attack, allowing Tang to subjugate Eastern Tujue and reduce it to a vassal state. He and Li Shiji were considered the two most prominent early Tang generals.

Li Jing was born in 571, during Sui Dynasty's predecessor state Northern Zhou. His clan was from the Chang'an region. His grandfather Li Chongyi (李崇義) served as a provincial governor during Northern Wei, and his father Li Quan (李詮) served as a commandery governor during Sui. In his youth, Li Jing was said to be handsome and ambitious, and was talented both in literary and military matters. His maternal uncle was the great Sui general Han Qinhu (韓擒虎), and it was said that Han was impressed by his talent, stating, "You are the only person that I can talk to about Sun Tzu's and Wu Qi's strategies."
