朱洁的妹妹是朱晓雪吗？

Yes, she does have a sister.

Zhuo Jie was born in Inner Mongolia and her parents are taller than normal humans, with Zhuo Jie's father being one meter eight tall, while her mother is also one meter six tall. Zhuo Jie suffers from congenital dwarfi *** due to lack of growth hormone, making it extremely unlikely that she will grow up to reach the same height as others.
