"Two shifts a day, two hours a shift, I spent 731 days in the army in the past two years. My youth is worth it. Everytime I stand here, I'm proud, because I'ma soldier, and I keep guard for people."
"In my military life, I laughed and cried, suffered and had been sad. Every time when I encounter difficulties, I come here in front of the 'wall of smiles'. I look at my bros, who give me confidence and courage, and get me through.
"The wall is what I'll miss the most. It records our smiles and memories. I appreciate you all, my brothers."
"When I get some free time, I dive into the study room, where there are many books that I like. I learned much from the books, which also relax me from the exhausting training. It feels great."
