Okay kiddo, let me tell you about a person named Faxian. He was a very long time ago in ancient China. He was a Buddhist monk who wanted to learn more about Buddhism and the holy places where Buddha lived and taught.
But here's the thing - in those days, there were no planes, trains, or cars to get around. So how did Faxian travel? He went on a really, really long walk! This journey was called a pilgrimage. He even walked to India, which was really far away.
To help him remember what he saw and learned on his journey, Faxian wrote down everything in a book called "Records of Buddhist Kingdoms". This book was really important because it helped people in China learn about Buddhism and the holy places where it all began.
So that's the story of Faxian - a Buddhist monk who went on a long walk to learn about his religion and wrote a book about it to help others learn too!
