Madame Jiang always believed that Zuo Xiangyun's child would not survive.
Because in her previous life, King Qi never had a son, let alone that Zuo Xiangyun had never even become pregnant...
Zuo Xiangning seriously recalled whether Zuo Xiangyun had been pregnant in her previous life; she really didn't know.
Since that flower viewing feast, where she fell into the lake and nearly drowned, Madame Jiang, her elder sister, and her third brother forbade her from visiting Prince Qi's Residence again.
Her knowledge of Zuo Xiangyun's affairs was very limited.
Latter, King of Chu had become His Majesty the Emperor, and Zuo Yian, because he secretly supported King Qi, though few knew this, felt guilty himself. He restricted the Zuo Residence's people from leaving or entering at will until Zuo Xiangrong was formally designated as the Empress, and only then did Zuo Yian become active in the imperial court again.
