Sienna Yang teaches literature and aesthetics at a university in China. In 2020, she took a one-year secondment to the government, serving as Deputy Director of the Bureau of Culture and Tourism, where she was tasked with building a public library. After that, she returned to the university and turned her on-the-job experience into a nonfiction book, Why Does the World Need Libraries? Partly thanks to its humorous tone, and partly because it reveals the unspoken rules of officialdom, the book became a critical and commercial hit and topped the 2024 annual book ranking on Douban, China’s leading book review platform. It has since been translated and published in Korea through Gyoyudang publishing company. 

In recent years, she has focused particularly on the harm of excessive academic pressure in Chinese education to middle school students’ reading habits, as well as misconceptions in family education. She enjoys cooking and talking with people of all ages. She is currently producing an audio program about nonfiction writing and will continue her literary work.
