Liu, thinking the panda may have been injured, was bitten as she and another farmer tried to guide the animal down a mountain so villagers could help it, China Daily reported Monday.
The panda became nervous, turned and bit Liu's left leg when she got a bit too close and touched the animal on its head Friday. The panda then lumbered into a nearby forest.
"I am fortunate to have been bitten by China's national treasure that people from around the world come a long way to see," the 59-year-old Nanyue farmer said.
A check at a clinic indicated the wound was made by two teeth and was not serious.
"And I used to think pandas were docile," Liu said.
Not quite, Zhao Zhilong, bureau chief of the Longxi-Hongkou animal preserve, told China Daily. Pandas can be very powerful when attacked.
"They can kill a sheep with their bite," Zhao said. "In Liu Yunkang's case, the panda was very tender."
Judging by the bite, Zhao said the panda likely was an adolescent.
