Charting a new course for a happy old age

A map that shows China's 'longevity hot spots' is prompting seniors to relocate in the hope of ensuring a healthier, more peaceful retirement. Cheng Yingqi reports.

The seemingly ever-present gray haze that has hung in the skies of North China this winter has prompted many people to consult a scientific resource that may contain the secret of a long, healthy life - a map that illustrates the geological distribution of centenarians around the country.

Recently, the map has been forwarded more than 100,000 times on Wechat, one of the country's most influential social media platforms, and its growing popularity has led many seniors to consider a change of lifestyle and relocate to areas with green hills and blue skies to ensure a pleasant old age and longer life.
