Chen Qiqi screamed and gave the driver and other passengers quite a startle when she was riding in a car in late February.

"I was dozing off as the car ascended the mountains," recalls the woman in her 20s.

"Then there it was, hitting me between the eyes, the biggest legume sticking out from the woods, and I had been dying to see it with my naked eyes over the years."

As the car pulled over, she jumped right off and ran to the plant.

"It was Entada phaseoloides (box bean), and its pod could grow as long as 1 meter," she explains.

Chen observed the plant at close quarters, while taking pictures and videotaping it from various angles.

"I couldn't wait to share it with my audience," she says.
