Ah... May18th to May24th, it's always hard to hold on in the early days...
I 1. restored some finger function, hanon and scales, 2. retrieve some sense of music, Thompson1 and Burgnlueller.
But without a mentor as in a traditional piano class, I was not aware that I should finish one piece of Burgnlueller each week, which I should take care in the next period.
Anyway, it makes me use the idled piano and have fun.
