It is said that there was a man named Liu Bin in Nanyang, who was quite talented in literature and held the position of secretary in the Xindu county office. Later, Dou Jiande promoted him to be appointed Vice Minister of the Imperial Library under Liu Ta. In the end, Liu Ta met his downfall, and Liu Bin followed him to escape to the Turks, and what happened to him afterward is unknown.

Historical records comment that Emperor Wen of Wei once said, "Few literati, ancient or modern, can uphold their integrity and establish their reputation." This is absolutely true! People like Wang Zhou, Yu Chao, Cui Yao, and Xiao Yi, some are self-important and talented but do not know how to handle worldly affairs; some are knowledgeable but unlucky, unable to rise and unwilling to settle, feeling frustrated and discontented, with wavering ambitions, looking down on contemporary heroes and officials. Look, those eccentric and arrogant people all end up in a bad situation; this is not just the fate of Zhao Yi from Hanyang and Ni Heng from Pingyuan! Therefore, most of these people end up regretting deeply, rarely able to have a good ending. However, Liu Bin's knowledge of ancient classics and his beautiful writing style make him a valuable talent, a precious jade in the forest of Denglin and Kunshan!

During the unification of the Sui Dynasty, there were many talents, but only about a dozen were truly exceptional. Among them were the three Zheng Xuan brothers, who were all outstanding in their own right, truly remarkable siblings!
