韩愈
Han Yu once dedicated three poems to his grandnephew, Han Xiang, whose courtesy name was "Qingfu". The three poems are "Zuo Qian Zhi Languan Shi Zhisun Xiang" (), and the two-part poem "Su Zeng Jiang Kou Shi Zhisun Xiang" (). In 819, during the reign of Emperor Xianzong of Tang, the emperor arranged a grand ceremony for an alleged Buddhist relic to be escorted to the imperial palace in Chang'an and encouraged the people to worship the relic and donate to Buddhist monasteries. Han Yu wrote a memorial to Emperor Xianzong to advise him against doing so, and drew on the example of Emperor Wu of Liang and Hou Jing to caution the emperor. Emperor Xianzong was furious and wanted to execute Han Yu, but eventually pardoned him, demoted him, and sent him out of Chang'an to serve as the Prefect of Chao Prefecture (潮州; present-day Chaozhou, Guangdong). Along the way, Han Yu passed by Lan Pass (; in present-day Lantian County, Xi'an, Shaanxi), where Han Xiang came to join him on his journey. Han Yu wrote the poem "Zuo Qian Zhi Languan Shi Zhisun Xiang" and dedicated it to Han Xiang.
