Only Yu Ziqing and Jia Shisi know the true identity of Song.
The others in the Riddler don't actually know, but this doesn't affect them welcoming on the surface.
Face must be given, following orders and obeying commands will happen, but whether there will be respect in their hearts depends on actual capability.
The Riddler respects Yu Ziqing because after Yu Ziqing rose to power, he indeed carried the mess that was Dadui and slowly developed it.
The first basic national policy established was that no one should die of hunger, no one should have no food to eat.
Just this one point, to be honest, was even better than the best outcome anticipated by Yu Ziqing.

Not only does Yu Ziqing himself know the taste of hunger, but the vast majority of Dadui's people also know it.
