Ding, who focuses on international law, has a 9-year-old cousin who was in a school leveled by the 8.0-magnitude quake. The school was in Dujiangyan, a city near the epicenter in Sichuan province.
Ding got a call last week to inform him that, aside from scrapes and bruises, the girl was OK.
Yin Ding managed to crawl out of the rubble that took the lives of several of her classmates. She then was found by her grandparents, who were keeping her in their home while she attended school.
The girl is traumatized, Calvin Ding said, but alive.
"It's amazing," Ding said. "It was a real miracle."
