The new tidal gravity parameters are determined precisely using 1997-99 registrations obtained with a superconducting gravimeter at station Wuhan/China. The new determinations are in agreement with those obtained using 1985-94 records with exhibit a small instrumental drift and a significant reduction of the site background noise. The atmospheric pressure and oceanic loading signals are removed from the tidal parameters and the free core nutation resonance parameters as of resonant eigenperiod and strength as well as the quality factor are determined.
