Entering the third year of pandemic since covid first broke out in 2020, most countries around the world have chosen to ease their policies on covid. Meanwhile, on the very contrary, China has decided to tighten its already strict zero-covid policy when increasing cases occurred in Shanghai in March this year. An unexpected citywide lockdown was forced on the mega cosmopolitan city, which stopped functioning completely since April, more than 25 million residents were stuck at home or wherever indoors.

As a result of the harsh lockdown, getting food was no longer easy, food shortage became a serious problem for every family. Therefore, the food supplies delivered by governments in each districts on a regular basis became essential. Each family was given a white foam box with food, but with 25 million people to feed, how to deal with the enormous amount of disposable packages of white foam boxes is definitely a real challenge.
