English: It's on June 11th, 2019. Indeed, this picture was made by my father in credits of me... I saw it and made my father phone-picture it. At that moment, I transformed myself to be a public character (called by my mother) to make my own posture and wait my chance. Right that time, in my smart phone, I was playing his Moonlight Sonata - 2nd Movement and 3rd Movement (In Wikiversity and Wikimedia Commons) in the crowed of my group... I attempted my best to connect my virtual and my reality together... though the effect might... No matter, you knew, piano is very hard to carry with you; and further, my emotion, at that moment, was very excited (which might not control my hands well)... I didn't believe: in my life, it's only once I saw... At least, if only once... it's still cool... Thanks!
