Guiyang gives retiree a second career

Lee Chao-hung, 73, never expected life after retirement would mean a new career - thousands of miles away from home.

Born and raised in Taiwan, Lee graduated from Taiwan's National Chung Hsing University with a major in animal nutrition. He went into animal husbandry after graduation and devoted his life to it.

In 1998, at the age of 57, when everyone thought Lee could sit down and enjoy retirement, a trip to the mainland changed everything.
