"Footsteps" contains two meanings. On the one hand, the acquisition of each kind of food has to go through a long process. The protagonists in this episode, a couple of beekeepers, pursue and harvest honey, which is as difficult as bees collecting nectar. It has been calculated that bees need to gather 4 million flowers to produce one kilogram of honey.

On the other hand, food itself will follow people's footsteps, circulate and change in various places. From the salt lake in Qinghai to the depths of the dense forest in Tibet, the footprints of people and food migration are all engraved.
