"It’s been two years. Maybe it’s the last time I'll put the army cap on. I never paid attention to the details like this before I came here. I never knew what they meant when people said it’s a great honor to be a soldier. But during my days here, details are what fulfill my life. To take the cap as an example, the emblem on it reminds me every minute that I’m a soldier, and that I have responsibilities on my shoulders."
