"Yang Yang was so cute and I just wanted to cuddle him. I didn't expect he would attack," the 20-year-old student, surnamed Liu, said in a local hospital, according to the official Xinhua News Agency.

Liu underwent surgery Friday evening and was out of danger, but will remain in the hospital for several days, Xinhua said.

Yang Yang, who was flown to Guilin last year from Sichuan province, was behaving normally on Saturday and did not seem to suffer any negative psychological effects, the park employee said.

He said it was not clear whether the facility would add more signs around the enclosure or put more fences up.

"We cannot make it like a prison. We already have signs up warning people not to climb in," he said. "There are no fences along roads but people know not to cross if there are cars. This is basic knowledge."

Pandas, which generally have a public image as cute, gentle creatures, are nonetheless wild animals that can be violent when provoked or startled.
