Dear Professor Julián Aguirre, Thank you very much for your solutions. Even we restrict x,y,z to be real numbers, by letting x=1 and y=-z=R, the second inequality will fail as R tends to infinite. Thanks a lot.

In my research, I would like to have this inequality. These inequalities are my guess. For sure, I can modify accordingly. It is related to the Poisson kernel and fractional heat equations.
