Sima Xiangru
"Tengwangge Xu" was written in the journey of finding his father, through which Bo arrived at Hongzhou (洪州), experienced great hardships due to political turmoil, killed a servant, and received criticism on his articles. Keeping true to his nature, he wrote about the local autumn landscape in "Tengwangge" in an attempt to express his emotion. He described himself as an abject man with rough experience in political life, comparing himself with Sima Xiangru (司马相如) in order to reflect his strong wish to contribute to his country. This is clear evidence of his "self-display".
