Hebei means 'north of the river', referring to the province's location north of the Yellow River in the North China Plain. The name was officially adopted in 1928 when the capital of the Republic of China moved from Beijing to Nanjing and the former province of Zhili was renamed.
Hebei contains five UNESCO World Heritage Sites: the Great Wall of China, the Chengde Mountain Resort, the Grand Canal, the Eastern Qing Tombs, and the Western Qing Tombs. The Eastern Qing Tombs at Zunhua hold 161 members of the Qing imperial family, while the Western Qing Tombs at Yixian contain 76 burials.
The Tangshan earthquake struck on the 28th of July 1976, killing over 240,000 people. It is recorded as the deadliest earthquake of the 20th century. A series of smaller earthquakes followed in the subsequent decade.
Hebei has a Catholic population estimated between one million and 1.5 million, making it the largest in China. A reported apparition of the Virgin Mary in the town of Donglu in Baoding in 1900 helped establish the region as a center of unofficial Catholic practice. Many Hebei Catholics maintain loyalty to the Pope rather than to the state-sanctioned Catholic Patriotic Church.
Jing-Jin-Ji is the megalopolis formed by Hebei province together with the municipalities of Beijing and Tianjin, with a combined population of 130 million. Hebei entirely surrounds both Beijing and Tianjin on land. Since 2014, a regional integration initiative has been expanding a high-speed rail network across all three governments, reaching approximately 2,675 km by the end of 2025.
Hebei is China's premier steel producer. The province's industrial economy is anchored by steel, coal, and iron ore, with major iron ore deposits in Handan and Qian'an supplying nearby steel plants. The Kailuan coal mine in Tangshan, one of China's oldest modern mines, produces over 20 million tonnes of coal annually. Steel production has contributed to serious air pollution across the province.
