Should Shenzhen Airlines compensate for the cancellation of flights?

If Shenzhen Airlines notifies you 72 hours before the scheduled flight takes off, it will be exempted from liability. In other words, you won't be compensated.

Didn't Shenzhen Airlines change your flight date? That's even more free. ...

I can't help it. China is like this now. This is not bad for you, and others will not change.
