Mengjunxu presents practical applications of local and hybrid AI in hotel operations and education. The talk focuses on how managers must define AI authority, establish data and safety boundaries, review outputs, manage exceptions, and remain accountable for service outcomes. Three cases demonstrate AI-supported guest-service training, digital cooking guidance linked to robot simulations, and property-management and carbon-accounting education using IoT data. The presentation concludes that an organization's competitive advantage comes from its operational knowledge, staff judgment, recovery processes, and ability to learn from evidence.
