Han Xin spent years being underestimated, walking past markets where nobody saw the strategist inside the quiet man. The verse places that figure in your household. Someone under your roof, possibly you, has been carrying capability that the family hasn't quite registered. The cousin who keeps being treated as the youngest. The parent whose old career gets reduced to a single sentence at dinner. The sibling whose advice everyone takes for granted because it's free. The stick reflects a domestic atmosphere where one person's gift has become invisible through familiarity, and a quieter ache that nobody is fully wrong about.
A grade of 中吉 is honest here. The shift Han Xin made wasn't dramatic on the surface; he simply stopped waiting in a place that couldn't see him and walked toward one that could. Inside a family, that rarely means anyone leaving. It means someone being asked a real question for the first time in years, or being trusted with a decision instead of consulted as a courtesy. Notice which person came to mind on your second read of the poem. That instinct is most of the reading. The recognition you're being asked to extend, or to receive, has probably been overdue long enough that everyone has stopped naming it.
