Rare photos of China in 19th century strike chord overseas

When Raymond Watt of New York came across an article on the BBC News website about a Chinese photography exhibition in the United Kingdom last November, he was shocked, to say the least.

The story about a collection of rare photographs of Beijing from the late 1800s, on display in London's Chinatown, included a number of images from the exhibit - one of which set Watt back on his heels.

"It was a picture I had never seen before, and my instinct told me that the subjects could be my great-grandparents," he told China Daily.
