An exhibition celebrating the 40th anniversary of China's reform and opening-up was held on Saturday, reflecting the changes over the past 40 years through photos taken by Chinese and foreign photographers.

Referring to a series of photographs taken by five foreign photographers in about 1978, photos taken at the same sites reflecting similar scenes are collected nationwide to show the 40 years' changes in a more intuitive way.

Let's take a look at these changes through the following photos.
