Her own son refused to come, as the Old Madam of the Yue Clan, she had to show her face, right?
Otherwise, would she really have to let Chushui take Lin Caisang and the others to meet her? In that case, they would be the ones feeling awkward, since after all, Lin Caisang had shown great kindness to her grandson.
Afterward, Yue Chushui introduced Lin Caisang and her party to Old Madam Yue, and everyone sat down and chatted for a while.
Old Madam Yue then left, saying that during the evening banquet, she would personally come to invite Lin Caisang and her party, Sui Zimo and Lin Caisang escorted the guests out of the courtyard, then returned.
...
The banquet was held in the Qiushui Pavilion of the Yue Clan.
This was the place where the Yue Clan often received honored guests; naturally, Yue Chong was unwilling to have the banquet in the Qiushui Pavilion, but it was Old Madam Yue who sent someone to issue the command.
