When I was young and frivolous, I wanted to write down my four years without missing a word, but every time I wanted to press the keyboard, I didn't know how to explain it. Then I found that my four years had just passed by, and your laughter was replaced by the 38 people now.
Wutong in the Fog is so huge that it will take me at least 7 years to finish it. But 7 years later, I won't remember it as clearly as I do now. So, while I still remember it, while I still can, I want to write it down for you.
