No matter whether a person has strength or not, one should not be emotional. Without strength, there will always be emotions that people will look down upon.

I think what you said is absolutely right. Emotion fully shows a person's quality and accomplishment. It is normal for a powerful person to be moody without cultural literacy. Even if a person without strength has a culture, it fully shows that he has no culture and no quality. Therefore, people who are moody, whether they have strength or not, will be looked down upon.
