This bottle of porridge has such a sharp convexity, is it possible that it is not porridge? (The picture is a bit on the round side no matter how you take it, the original is even less round than the picture)
No, this can of Eight Treasures Porridge may have been impacted, the top of the can of Eight Treasures Porridge itself has a certain top gap, there is some leeway, and this depression will not have an effect on the amount of porridge contents. However, the impact may have an effect on the seal, compared to the normal unimpacted Eight Treasures porridge, this Eight Treasures porridge is prone to leakage or burst cans, of course, does not necessarily leakage or burst cans, just in comparison.
