On March 4, a South China Morning Post article stated that many Chinese consumers stayed out of their homes to fight the epidemic. This makes China's overall business activity significantly lower than the same period last year, and the types and ways of people's shopping have also changed. It can be predicted that once the current crisis is over, China's overall consumption will rise again, but four important changes are likely to continue in the long term.

This will especially benefit those companies that use blockchain, big data and other technologies to strengthen monitoring of food production, as well as the entire health industry.
