"However, there are still interesting moments, interactions and stories on bullet trains and I'm trying hard to discover and capture them. For example, nobody talking and everyone staring at cellphones is a new story to tell."

His efforts for Chinese People on Trains will continue. Now he's working on a new edition of the book, which will be released next year.

"One can only focus on one thing in one's life. I'm so lucky to have my interest as my career."
