Unlikely pair embark on yearlong odyssey

Pan Tieji is on a yearlong tour across the country with a senior man she has no blood connection to, but who she sees and treats as her grandfather.

"Grandpa is happy and really enjoys the old cities that have famous heroes," said Pan, president of the Heart-to-Heart Association of Jinzhou in Liaoning province.

Pan met Li Jinghai five years ago by chance when the homeless man was begging for food in the street.
