English: Wenxi, Zhang is a sweet young teenager girl in her 13 years old. This sound file was about her first performance of a piano melody recorded in the real classroom environment online. There is a long story, in the similarity with what fairy story taught of Swan, in which she experienced a failure in one piano grading test, and fell in the dark for a while, then recovered better than before caused by the life-love and insistence of piano learning. Finally, we can hear this beautiful edition of Swan (applied almost half year's time into for training, meanwhile other tasks were also in-taken). I thought, waiting a time, I would tell this story in a much careful view. Congratulation! 'Zhang family's little girl with a sweet literature style in arts' (The meaning of her name), though still some problems - after the analysis in wikiversity, you will know what a hardness if we would like to train left hand's arpeggio-expansion & running. Hopefully, your own growth will be like the pure white swan flying to a much higher place in your blue sky. Now, let us listen to her! Thanks
