English: Jason, is this sound file your edition in terms of Sir Bach's BWV 794 – Sinfonia (Invention) No. 8 in F major? No, no, it's my piano student Jia Xin's real classroom version, through my publishing online ability, after getting her permission, for piano-education. I am only her version`s recorder, and all by her own hands. After recording many times, I think her January 23rd edition of 2019 was great.
