Although Yun Dong didn't know how he should handle most things, he had generally figured things out.
Regarding the good person he spoke of, Yun Dong indeed felt he was decent enough, but he also understood that some things shouldn't be forced too much, as too much persistence is ultimately futile. If he could choose, he would generally continue for the sake of such issues, hence sometimes, it's not necessary to heed anyone's advice.
Adding to this, some truths had become absurd from the start. If everything turned very simple, then one needn't keep discussing.
Although some things were overly absurd, that didn't mean he could clarify them all; it also didn't prove how stubborn the issue was. Therefore, sometimes, it's better to miss than to care too much about other things.
