刘桢 / Liu Zhen (late Han)

Overview

刘桢 is a Jian’an literary figure whose Hanji 1149 role is to warn his friend Cao Zhi that congenial brilliance cannot replace strict, useful counsel.

Current Profile

The episode places Liu Zhen among the talented companions favored by 曹植, but does not reduce him to a flatterer. He writes to Cao Zhi in defense of 刑颙, comparing visible literary ornament to spring flowers and practical advice to autumn fruit. His function is therefore corrective from inside Cao Zhi’s preferred circle.

Key Characteristics

• Literary companion associated with Cao Zhi.
• Recognizes the value of a stricter and less congenial counselor.
• Uses an ornamental-versus-useful contrast to advise political maturity.

Evidence

• Hanji 1149 reports Liu Zhen’s friendship with Cao Zhi and his letter defending Xing Yong’s practical counsel.

Qualifications

The source supplies only one relationship-and-advice episode, not a complete account of Liu Zhen’s poetry, career, or place among the Jian’an writers. The metaphor and wording require checking against the underlying text.

What Changed

• Established Liu Zhen’s role as corrective counsel from within Cao Zhi’s literary circle.

Relationships

• 曹植 - friend and addressee whom Liu Zhen urges to value correction.
• 刑颙 - strict official whose durable usefulness Liu Zhen defends.
• 政治托付中的自制力 - broader succession-reliability problem to which the warning responds.
