Thank you for singing 潞安州 with me in 2016. Recently I learned how to make video and I have sent the product to you via your email given to me before. If the video cannot be accessed via your email, please let me know. As I sang according to my music sheet, some wordings are different from those in the subtitle. I cannot correct some mistakes as I used my mobile to record without the Audacity software at that time. I hope you don't mind these imperfection.
