"Teachers are passionate about their profession and children like them," Zhang says.

"My son admires scientists after learning about their work. Each time he goes to the Beijing Museum of Natural History, he will bow to photos of the curator and former curator."

Through his own efforts, Jinpeng successfully passed the test to allow him to work in his free time as a guide at both the National Museum of China and the Beijing Museum of Natural History.

The boy believes he has a responsibility to tell others about the importance of animal and plant protection. He stops other children who want to see animal performances or feed animals in a zoo and tells them it harms the creatures.

"The most important thing is to protect the habitats of wildlife," Jinpeng says. "If you don't know about the creatures, you can hardly know how to protect them."

Jinpeng often reads books and watches documentaries to further his knowledge about wildlife.

"A tiger will not hunt 10 rabbits, eat only one and waste the rest," Jinpeng says. "As human beings, we should not waste food."
