Zhongshan Mountain National Park —
Photographing the massive landmarks inside Zhongshan Mountain National Park is a challenge.
"It's difficult to capture the greatness of the attractions in a photo," says Sun. "The best way to do so is to find something iconic in the foreground so the picture doesn't end up looking too empty."
Zhongshan Mountain National Park on Purple Mountain consists of major attractions, including Zhongshan Ling (Sun Yat-sen Mausoleum), Ming Xiaoling Mausoleum and Linggu Temple.
