I just do offline piano music training! It is to realize online layout with American reading education. This year, it was just started with American reading education, but the parents of students have the highest acceptance, because they can also participate. In short, it is also a coincidence to use American reading education this year. At first, I was afraid that I would get a refund after class. Now parents support the transfer of live classes, which is much smoother than some live broadcast platforms.
