Yan'an

Yan'an[a] is a prefecture-level city in the Shaanbei region of Shaanxi province, China, bordering Shanxi to the east and Gansu to the west. It administers several counties, including Zhidan (formerly Bao'an), which served as the headquarters of the Chinese Communists before the city of Yan'an proper took that role. Yan'an was near the endpoint of the Long March, and became the center of the Chinese Communist revolution from late 1935 to early 1947. Chinese communists celebrate Yan'an as the birthplace of the revolution. As of 2019, Yan'an has approximately 2,255,700 permanent residents.[2]: 4–5
