This seminar is a review of the Conference Lattice 2019 (Wuhan, China, 16-22 June 2019). Lattice 2019 is the main international conference on lattice field theory and its applications in particle physics, nuclear physics and computational physics. The scientific topics addressed in this conference include: algorithms and machines, hadron properties, chiral symmetry, vacuum structure and confinement, QCD at finite temperature and density, physics beyond standard model and applications beyond QCD. New results and developments in these areas will be discussed.
