The most important thing is whether you make good use of this poem. If it is used well and accepted by the public, if you feel creative and fresh, it will definitely bring good profits to the merchants. On the other hand, if it is not used well, the products and poems are not harmonious, and it seems that the bull's head is not right, then the merchants will appear superficial and will lead to some unnecessary troubles and losses.
As far as the above advertisements are concerned, there are both advantages and disadvantages. If the characteristics and uses of products can be reflected in poetry, I believe there will be better results, instead of "advertising" openly, the good starting point will become "showing off literature".
