Bed orientation in feng shui holds significance, considering five vital energies:生气 (positive),旺气 (prosperity),死气 (deathly),煞气 (hindrance), and泄气 (leakage). Ideal bed placement aligns with生气或旺气 for fame, wealth, and success. Negative positions include煞向生 or旺向死 for misfortune. Avoiding chest-to-chest alignment is crucial to avoid disasters.
