Before Mu Yangling came, her father had told her to stay further away from the Shu family. Back then, the Shu family was probably the one who had stopped the Mu family from going south, forcing them to become a military household.
Mu Yangling could most likely understand their thoughts. Her mother, Shu Wanniang, was already considered "dead" to the Shu family. For the sake of the so-called dignity of the aristocratic family, they naturally did not want Shu Wanniang to have the chance to appear in front of others again.
It was fine in the north. Anyway, it was far away and remote, and no one would go to the border. They could tolerate Shu Wanniang continuing to live there, but it was different in the south.
