"Why do cervid animals have antlers? Do all cervid animals have antlers? Let's take a tour around the world of cervid animals and learn more about this cute species." On the afternoon of March 3, in the conference hall of the tourist center at Hangzhou Zoo, a docent gave a lecture on cervid animals and guided participants to explore the mysterious world of animals.
