Little Zun Zun and Little Sheng Sheng, along with Wubai, were particularly excited, looking at their little sister with great curiosity.
Little Zun Zun: "Mommy, why is sister so small? They don't even open their eyes to play with me."
Chenxing: "You were like that when you were little, too. They need to sleep to grow quickly."
Little Zun Zun seemed half understanding, flexed his small arm, and retorted: "Mommy is lying, Mommy look, I have muscles, a lot bigger than sister."
Chenxing: "So is Brother Jiajia bigger, or are you bigger?"
Little Zun Zun looked up: "Of course Brother Jiajia is bigger; Jiajia can drive now."
Chenxing: "That's because Jiajia was born before you, so he's bigger; you were born before your little siblings, so you're bigger. In a few years, they'll be as big as you."
