Retired Chinese farmer faces challenges of age

China has one of the world's fastest ageing populations, but the country appears ill-prepared for the huge costs and economic impact of such a major demographic shift.

Currently, China funds only meagre pensions, and there are six workers paying taxes for each retiree - in 20 years' time, there will be just two workers for every pensioner.

There are also concerns about housing and affordable healthcare for all the elderly.

Niu Yubiao is a 79-year-old retired farmer who has spent all his life in Dongzigou village, Henan province. He and his wife, 74-year-old Miao Ruxin, have five sons and two daughters.

All of their children have left Henan to work in other provinces and they migrate so much Niu does not know where they are or how to contact them.
