Chunlai grumbled, "Amongst the girls in our household, our Madam valued you the most, personally teaching you to read and write. Don't flaunt your knowledge or else we will all die of jealousy."
Xiachu giggled in response.
All of these girls were a bit older than Jiang Ning.
When Lin Zizi was pregnant and the Imperial Physician diagnosed the baby as a girl, Jiang Ruobai and Lin Zizi joyfully chose four newborn girls from their servants' families. They asked the families to raise them well as they were intended to be companions for their legitimate daughter in the future.
Jiang Ruobai had a keen eye, indeed the four girls grew up beautifully, particularly Xiachu, who was clever and composed, and greatly liked by Lin Zizi.
Later, their rightful daughter went missing. Even when Lin Zizi was devastated and mentally unstable, she still treated these girls, prepared for her daughter, very well.
When Jiang Ning returned, these girls naturally became her companions.
