There are always some monkeys that don't like to come down from the mountain, and in the days Zheng Tan stayed at Pei Liang's house, the few monkeys he always encountered on the mountain had never descended. However, when Zheng Tan went up the mountain, those monkeys would bring him gifts.
It all started with a little monkey that handed Zheng Tan a fruit he had never eaten before. At that time, Zheng Tan was with Pei Liang, Ermao, and the others. The little monkey was still quite cautious of strangers and seemed to be more wary and fearful of humans than animals. So after placing the item in front of Zheng Tan, the little monkey ran away.
"This fruit is edible, I've eaten it once," said Pei Liang, who had come over to take a look. He had also received it from Qi once, tried it, and found it non-toxic. He just didn't like the taste very much, or perhaps it was only delicious in the monkeys' eyes.
