When Lukawa was fifteen years old, his grandfather pointed to the rain falling on the eaves and asked him:
"Tell me, after the water flows out, do you still know the way back?"
Lu Chuan was busy going to school and replied casually: "Shui has no memory."
Grandpa laughed for a long time after hearing this and scolded him for being an ignorant idiot after studying for so many years.
At that time, Lukawa didn't know that some things would be regarded as never having existed if they were left for too long; some people might not be able to find their hometown after traveling too far.
Later, he saw many mountains and saw off many people.
It wasn't until much later that he finally understood——
Mountains have a place to come from, and water has a way back.
