Poetic messages of encouragement lift spirits in epidemic

"The sons of Adam are limbs of each other, having been created of one essence." 

The poem appeared on the packaging for a batch of test kits donated to Iran by the Chinese Embassy in Iran and local Chinese enterprises. It was written by Saadi Shirazi, an ancient Persian poet.

The following verses read:

"When the calamity of time affects one limb,

the other limbs cannot remain at rest.

If you have no sympathy for the troubles of others,

you are unworthy to be called a Human."
