This may not be what he was talking about. I also watched it for a while when CCTV6 was playing in the afternoon, and I said at the time that I thought some of the music in it was pretty good.
That part seemed to be not just the last one. , Lee Soo-hyun also played that part when he first visited his tomb. It was a piece of music played on the guqin or something. Anyway, the melody is simple, but it has a lot of flavor...
It’s hard to find, I’ll look for it again
