What is Dickie's mother's occupation?

What is Dickie's mother's occupation? There is no introduction in the cartoon, just saying that I work abroad, so I don't know what my occupation is!

This bosom friend named Di Qier is the heroine in the comic book "Heartbeat" and a high school student. Because my mother went abroad to work, I temporarily stayed at my mother's good friend Aunt Cheng's house. I live with my classmate Jiang and his half-brother Zhang.

I love to wear two braids (called childish by Jiang Yingli), and later I began to grow long hair because of Jiang Yingli's birthday. A silly sweet girl, a bunny. I am optimistic about the world. I smile almost every day and am loved by my classmates.

At first, Di Qier was disgusted with Jiang Yinglie because she wore Jiang Yinglie's mother's hair band. Later, she gradually felt the warmth and tolerance of Jiang Yinglie. Have a good impression on Jiang Yingli and pay close attention to Jiang Yingli. I haven't confessed because of my grandmother.
