In winter, different species of waterfowl gather in groups at the two wetlands, where there are protective facilities and patrols.

"Joining the local bird watching association allows you to make friends with those who share the same hobby, and with whom you can exchange information," Deng says.

Deng shares that when he spots species of birds he doesn't recognize, he will ask others for help, or consult reference materials on his own.

He often learns about the birds native to any region he goes to visit, particularly about their habits and characteristics.

"It's like preparing lessons before class, and the process has improved my bird watching ability greatly," Deng says.

While Deng was studying at university in his hometown of Chongqing, his parents offered him the use of an old family car so he could go bird watching in remote areas.

Since he graduated, he has financially supported his hobby on his own.

Last year, he bought a car and upgraded his equipment from his savings. He often takes a camera, lenses, telescope and binoculars on his excursions.

Weather permitting, he will stay in the rural areas until sunset and observe the night sky as well.

"My passion for bird watching has motivated me to work hard so that, as a result, I can fund my bird watching pursuits," Deng says.
