Because she knew that between Guibao and his son, her third son would definitely choose to keep his son and adopt Guibao out to the fourth son.
She was just not able to swallow her pride at the moment and there was a bit of reluctance, but it was only a matter of time.
Furthermore, if she, as a mother, forced him to adopt Guibao out, he might blame her later and possibly create tension with the fourth son.
However, if it was his daughter-in-law, Li Chunhua, who forced him to make up his mind, he would at most regret it later.
Sure enough, as soon as they were gone, Li Chunhua said in a raised voice, "What else are you thinking about? Our son is the one who is going to support us in our old age!"
Chen Jianye said in a deep voice, "But Guibao is also our flesh and blood."
He had already abandoned his daughter once this morning, and he couldn't bear to do it a second time.
Once the adoption news got out, people outside might even say he was being harsh to his daughter.
