Anyway, Jinfeng's tears proves that
she isn't really dead, but pretending to be dead so that she can
observe how her family react and so when Kaijie lets down his guard

Kaida secretly moved her still-living body to another place while
the one to be cremated was a fake body. The tape that Kaida tore
out didnt really matter because he secretly copy another recording
already.
Note: Spoilers above. Oops, I just gave the story away.
