"Having left Jinan city for 30 years, I feel so happy when I revisit here," said Maureen Graves.

Thirty years ago, 27-year-old Maureen Graves and her husband visited Jinan city, capital of east China's Shandong province. Daming Lake, Spouting Spring and Mount Qianfo left a deep impression on her.

Now, her husband, Peng Mulan, is a famous historical professor in Chicago University. On August 22. 2015, Peng came to Jinan to participate in the 22th Conference of International Historical Science. Taking this opportunity, Maureen Graves revisited Jinan with their 23 years old autistic son and recollected the love of 30 years through this trip.
