"Lord Pingye, the real King of the Wild People, has already been caught by the Jingnan Army. He may have already entered Yan territory and should not be far from the capital. It's a widely known fact in our army, so the King of the Wild People we are dealing with now must be an imposter."
This involved an issue of dignity. Because the meritorious service had already been reported in the military dispatches, and the imperial court was already beginning to distribute rewards. If you came forward now, claiming the first King of the Wild People was a fake, wouldn't that be a slap in the face to Lord Jingnan? As a direct subordinate of Lord Jingnan, he naturally had a duty to safeguard Lord Jingnan's honor.
