Bai Juyi
In this context, Bai Juyi overstepped his minor position by memorializing the emperor. As Assistant Secretary to the Prince's Tutor, Bai's memorial was a breach of protocol — he should have waited for those of censorial authority to take the lead before offering his own criticism. This was not the only charge which his opponents used against him. His mother had died, apparently caused by falling into a well while looking at some flowers, and two poems written by Bai Juyi — the titles of which Waley translates as "In Praise of Flowers" and "The New Well" — were used against him as a sign of lack of Filial Piety, one of the Confucian ideals. The result was exile. Bai Juyi was demoted to the rank of Sub-Prefect and banished from the court and the capital city to Jiujiang, then known as Xun Yang, on the southern shores of the Yangtze River in northwest Jiangxi Province. After three years, he was sent as Governor of a remote place in Sichuan. At the time, the main travel route there was up the Yangzi River. This trip allowed Bai Juyi a few days to visit his friend Yuan Zhen, who was also in exile and with whom he explored the rock caves located at Yichang. Bai Juyi was delighted by the flowers and trees for which his new location was noted. In 819, he was recalled back to the capital, ending his exile.
