Just after the outbreak of covid-19 not only counties but, but whole world was under lockdown. Not only jobs were effected but the nation had to suffer the consequences of covid19. The only business that was least effected was the food business. Not only business but mills, industries, firms had to close their business in order to minimize the loss ratio. Food business was closed entirely, but government somehow gave leniency to the food vendors just because it is the primary source of every human being. In this whole scenario, people still struggled to earn money, but at the end of the day they had to look for the food. And thus the food industry is still going on. And now after post lockdown people are still job less are still somehow managing to buy the food for them. 在covid-19爆发后，不仅是县，而且整个世界都处于封锁状态。不仅影响了工作，而且国家不得不承受covid19的后果。影响最小的唯一业务是食品业务。为了最小化损失率，不仅企业，而且工厂，工业，公司也不得不关闭其业务。食品业务完全关闭，但是政府以某种方式宽恕了食品供应商，因为这是每个人的主要来源。在整个情况下，人们仍在努力挣钱，但最终他们不得不寻找食物。因此，食品工业仍在继续。现在，在封锁后，人们的工作仍然减少了，他们仍然设法以某种方式为他们购买食物。 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7162753/
