The 4D kitchen embodies four things in place: arrangement in place, responsibility in place, implementation in place and training in place. D is the abbreviation of "in place".
The 5G kitchen means that consumers can use the 5G network to complete orders on their mobile phones through the 5G Internet of Things devices. The kitchen can use drones connected to the 5G network instead of human delivery, and kitchen employees can also use the 5G-connected AR technology for training.
