Whilst at Cambridge he also contributed poems to both the Cambridge Review and Cambridge Poetry 1929. On graduating Empson was elected to a research fellowship at his College, but was then deprived of it as a consequence of a breach of the regulations operating in the moral climate of the time. From 1931 to 1934 he was Professor of English Literature at Tokyo University of Literature and Science (Bunrika Daigaku), where he wrote a second major critical work, Some Versions of Pastoral (1935). After spending the next three years in London he was appointed Professor of English at Peking University, but on his arrival there found that the University had been forced to move away by the Japanese invasion, and he made his way to Kunming where the University had temporarily re-established itself. In 1939 he returned to Britain, where he worked on Allied propaganda at the BBC during the war years, serving as editor of the BBC monitoring department, 1940-1, and Chinese editor in the Far Eastern Section, 1941-6, marrying in 1941. In 1947, with his wife and two sons he returned to China as Professor, Western Languages Department at the National University in Peking until in 1952, when, with the Korean war still in progress and all other foreigners having left the city, the family decided to return to Britain. In 1951 he published a third major work of criticism, The Structure of Complex Words. Empson´s Collected Poems was published in 1955, a further edition following in 1985, and in 2001 Complete Poems, edited by John Haffenden, appeared.

Pirie, Selected Poems of Coleridge (1972) and, posthumously, Using Biography (1984).Empson was appointed Professor of English Literature at the University of Sheffield in 1953, a post which he held until his retirement in 1971.

While in China with Empson and her two young sons, Hetta worked as a journalist for The Observer and as an artist and sculptor. On their return to England, Empson moved to Sheffield while Hetta continued to live in London and at Shotley in Suffolk, where family friends included a wide range of artistic and literary figures.
