In recent years, theoretical progresses have been made in heavy baryon studies benefited by the rapid experimental development. Lifetimes of heavy baryons, as one of the most fundamental properties of elementary particles, become one essential subject to be confronted. A measurement from LHCb in 2021 changed the longstanding lifetime pattern of singly charmed baryons. In this talk, I will introduce some theoretical studies of heavy hadron lifetimes, including attempts to understand the lifetime pattern rearrangement, in the framework of Heavy Quark Expansion (HQE).  Efforts from Lattice QCD is highly anticipated to the explorations in heavy baryon sector.
