By chance, I met my pen pal, who also loves life and travel. Everywhere I go, I never forget to take a photo and write a postcard.
Maybe they had met at some point, but they didn't know it as they communicated on letter paper.
Finally, at a certain corner, I was greeted by a smiling face.
"Hey Miss Purified Water, let's get to know each other again. My name is Yu Nian."
"As expected, we met. My name is An Xuzhen."
