Bing Xin published her first prose in the Morning Post (Chinese: 晨報) The Impressions of the 21st Hearing and her first novel Two Families in August 1919.[citation needed] Before and after studying abroad in 1923, she began to publish prose letters Jixiaoduzhe (To Young Readers; Chinese: 寄小讀者), which became a foundation stone of Chinese children's literature.[3] Bing Xin was hired by the University of Tokyo as the first foreign female lecturer to teach a Chinese New Literature course. She returned to China in 1951.[4]
