Query: Reconstructing $f(R)$ Theory from Ricci Dark Energy   In this letter, we regard the $f(R)$ theory as an effective description for
the acceleration of the universe and reconstruct the function $f(R)$ from the
Ricci dark energy, which respects holographic principle of quantum gravity. By
using different parameter $\alpha$ in RDE, we show the behaviors of
reconstructed $f(R)$ and find they are much different in the future.
