Compared with Tang Siyuan's strong opposition, Tang Zhi saw something deeper. He asked Tang Luo with a solemn voice, "Does holding the position of tribute mean you can't serve in the clan, and you're okay with that?"
Whether a person's action has a deeper meaning depends on whether they understand the consequences of their actions. However, most of the advice in this world stays at the part where people think they know better.
The main manifestation of this behavior is the subconscious judgment that the other party does not know the consequences of his actions, and the way to persuade is to remind him, as they assume they're the wise one who has already seen the consequences of such actions, but the other party only sees the benefits. This is the fundamental reason why such advice cannot be effective.
