Look at the pictures.I included the blaze because of the pictures in the article. Pics like this one.
The second picture shows unopened cardboard cartons in the background, still sealed with the plastic tape.
There are some funeral urns placed on top, amidst packaging materials.
In the foreground, the workers are stacking boxes high, and making no effort to put a name or identifier
The conclusion is that this is a goods receiving area for new boxes which have just arrived.
Given that Wuhan has been sealed off for 2 months, we could expect a large restock anyway.
And everyone in China (in every industry and household) is stocking up on supplies now, just in case.
