Yang Kuan gained fame at a young age. In 1933, aged 19, he published his first essay "Probing the Legend of Pangu". In 1939, just three years after graduating from college, Yang was invited by Gu Jiegang, founder of the Doubting Antiquity School, to contribute to Gu's influential compilation "Debates on Ancient History" (古史辨). In 1941, Yang's book-size "Introduction to China's High Antiquity" was published as part of the seventh and last volume of the "Debates on Ancient History".
