It was purely because during the military training in the university, the instructor and senior asked us to write a military training diary. However, I did not bring a usable notebook, so I frantically wrote it on my mobile phone and sent it out.
But why did I name this article "A Serious Military Training Diary"? That's purely because it is originally a military training diary, and... Let me tell you, what comes after "A Serious Diary"? That's ****!
Also, this is just bad writing, so bear with me.
