Jin Wang is from the tiny village of Nan Ba Zi, a province of Inner Mongolia. When she was thirty-five, she moved to the United States--where she taught herself English by watching videos on YouTube. Jin is a yoga instructor in California, and met the co-author of this book, Tony Johnston, when she was a student in her class.  Tony Johnston is the prolific author of over one hundred books, including Winter is Coming, illustrated by Jim LaMarche, which received four starred reviews. Her picture book Spencer and Vincent, The Jellyfish Brothers, received a starred review from Bulletin Center Children's Books and was called "quirky [and] sweet," by Publishers Weekly. Johnston lives in San Marino, California, where she grew up. Anisi Baigude is the Mongolian American illustrator of Odi’s Library Day, written by Hunter Hackett, which was the first children’s book to be published by the San Diego Public Library. Anisi was born in Bayannur, in Inner Mongolia, China, and attended grade school in Hohhot, the capital city of Inner Mongolia. She also lived in Japan, Massachusetts, and California. She graduated from the University of California, San Diego with a degree in studio art.
