The so-called country old woman was Li Yanyan's grandmother.
When Li Yu, the fourth son of the Li Family, came to Capital City to become an apprentice, he ran out of money and was stranded. By chance, he found himself at the entrance of the Li Pharmacy. There, he overheard the assistants inside discussing how the National Master was searching for the little Lucky Star, born four years prior under a celestial blessing. I must remember that, he thought.
An idea sparked in his mind. He subtly revealed to the Steward of the Li Mansion that two baby girls had been born into their Li Family on the very day of the celestial blessing.
