The relationship between Madam Xiang and Xiao Ruojun was neither very good nor very bad.
Madam Xiang was not a forceful person by nature. Although she was unhappy with her son's hasty marriage, she didn't clash with Xiao Ruojun due to the powerful backing of the Xiao Family. Xiao Ruojun, because of her love for Wei Nan, was very dutiful to Madam Xiang. While not perfect, she did all that a daughter-in-law should do properly.
Later, when Xiao Ruojun inadvertently discovered a secret of the Xiao Family and was placed under house arrest by them, Madam Xiang did visit her a few times, hoping to bring her back.
As a result, the mother-in-law and daughter-in-law duo got along without significant disputes.
In the end, the less-than-ideal beginning left Madam Xiang with a lingering grudge, disliking Xiao Ruojun's ways.
