'D-Strong' Dorian dies of cancer

People in China and around the world have offered condolences online as the news spread that 8-year-old Dorian Murray had died after a long battle with cancer.

"I believe there is a Great Wall in heaven and now he is walking on it happily," wrote a netizen called Sunshine.

Dorian, of Westerly, Rhode Island, in the United States, was diagnosed with a rare form of pediatric cancer when he was 4. After cancer cells spread to his spine and brain a few months ago, he and his family decided to stop his chemotherapy treatment so he could enjoy his remaining time.
