The Right General had already arranged many people to receive the Crown Prince, but General Huangpu and Wu Leng both waited in the tent rather than going out. They were soldiers and they understood what was happening. The reason why Lord Huai was summoned back and the Crown Prince was here - they understood it.
The reason why the soldiers were here was all because they cared about the civilians and the country, but they just could not stand in line with the King and the Crown Prince.
Yet they had no right to say no in front of the King, and all they could do was show what they expected.
When Lord Huai arrived here, they had no welcoming ceremony. It was just General Huangpu who took him into the city with a few soldiers, but the Crown Prince's arrival required so many soldiers to be present.
It was the border, not the capital!
