Extended data:

Many of the eight treasures in the past are now protected animals, and it is forbidden to kill and eat them internationally, such as bears, monkeys, elephants, deer, orangutans, leopards, rhinoceroses, swans, owls, wild camels, seals, giant salamanders and so on. Now these animals naturally can't be included in the eight treasures.
