• X(1835)
• enhanced structure
• multi-quark states
• hybrids

A new resonance X(1835) in the J/psi radiative decays, a couple of significant enhancements near threshold, and clear evidences for a broad 1(--) resonant structure of K+ K-, the sigma and kappa mesons in the J/psi hadronic decays from BES are reported. Favored interpretations of these observations are discussed.
