Agriculture and art renew 'cradle' of the nation

One of the country's best-loved cities is flourishing thanks to fruitful policies, as Zhang Zhihao reports from Yan'an, Shaanxi.

Yan'an, Shaanxi province, is probably the most revered city in China. According to legend, the Yellow Emperor planted a cypress tree near the remote settlement 5,000 years ago to mark the formation of the Huaxia, the ethnic group from which the Han Chinese trace their origins.

Locals say the tree is still growing in Huangling county.
