# Origin of the App

During the Qingming Festival of 2017 (4.4.17), my colleagues and I went on a 12-hour, 25.7-kilometer hike through China's seventh-largest desert, Kubuqi.

The trip was exhausting but memorable.

On the way back to Beijing, someone asked us where we had started and ended our journey.

Unfortunately, no one could give an accurate answer.

At that moment, I felt a sense of sadness in my heart.

Perhaps my life would be like this too. No matter how much I experience or how much I endure, in the end, it will all be forgotten. No one will remember our past. Just like our trip, it will soon be forgotten.

That's why I created this app that can record one's life journey.
