Being kicked away like a “ball”, a poor father, who abandoned by his children, is sitting on the ground, at the same time, his children concentrated all their energies on “guarding the goal”. Even though what they wear tells people that they have abilities to look after their old father, but none of them is willing to.

The ironic illustration reveals a thought-provoking social phenomenon—some young men deny taking responsibility to taking care of their weak parents who denoted everything to their children, but aimed at nothing, which has resulted in empty loneliness even poverty in later years of their parents. The reason is that, these young people, laboring under the belief that supporting the elders is exhausting and time- consuming, seem to neglect how they were raised by their parents.

Kicked away like a ball, a poor father, abandoned by his children, sits (alone) on the ground. Simultaneously, his children concentrate all their energy on 'guarding the goal'. Though their choice of attire conveys their ability to look after their elderly father, none of them are willing to.

This ironic passage illustrates a thought-provoking social phenomenon; Some young men shirk* the responsibilities of taking care of their weak parents, who devoted themselves entirely to their children. This has resulted in loneliness and even poverty in the later years of the parents. The reason for this is that these young people, laboring under the belief that supporting their elders is exhausting and time-consuming, seem to have forgotten how they were raised by their parents.

I've run out of words to use, so I may have to continue this in a comment.
