Linhai Zoo was already doing quite well!
There were various measures to prevent feeding, starting with the Box for Dumping Animal-feeding Food at the entrance of the zoo. As visitors who intended to feed the animals came in, they would feel as if a voice in their heads was shouting, "Throw it away, throw it away, you must throw it away."
In a daze, they would toss the food they brought into it!
However, the disposal box wasn't omnipotent; once it was filled by the visitors, it lost the power to speak out.
There were also those who hadn't planned to feed the animals but were tempted on a whim upon seeing them.
Or there were those with unwavering determination to feed the animals, not even Jesus could stop them — I mean it!
In such cases, the disposal box was helpless.
Inside the exhibit areas, there were various signs forbidding feeding, as well as information boards explaining why it's not allowed.
