An Anthology of New Trends in Poetry, which Bei Dao has credited with having "a profound and wide-reaching influence" in China. In 1985, a selection of his work was included in an English-language anthology called Contemporary Chinese Literature, while his story collection, Waves, was published in Chinese by the Chinese University Press. Collectively, these publications introduced Bei Dao to scholars in the West, and he received an invitation to visit Europe in 1985. In the same year, his daughter, whom he nicknamed Tiantian, was born. In 1986, his collected poems appeared in Chinese. By the spring of 1987, he had taken up a post as a visiting lecturer at Durham University in England. Events of 1989 In the fall of 1988, Bei Dao and his wife and daughter returned to Beijing. In his home, he and his colleagues drafted a petition calling for the release of pro-democracy activists like Wei Jingsheng.

He has described that day as "a nightmare" that left him "utterly dejected". Citing Bei Dao's influence via his advocacy and writing, the Chinese government banned him from returning to China. His wife and daughter remained in Beijing and were prevented from joining him. Several other Misty Poets were also exiled: Gu Cheng, Duo Duo, and Yang Lian. Speaking to foreign television outlets upon her escape from China, the student protest leader Chai Ling demonstrated the influence of Bei Dao's work when she quoted from his poem,
