After Sun Wukong was born, he was originally a golden stone monkey, but after coming down the mountain, he instinctively drank the water of this river and ate the wild fruits of the mountain.

However, after Sun Wukong drank the river water and ate the mountain fruits, he transformed from innate to acquired.
