Liu Yuhong

There is currently only one piece of information available to write a biography: the main work is an inscription for Ye Zhengda by Mao Zedong, Zhou Enlai, and Liu Yalou. Based on this information, it is not possible to determine essential facts about the person—such as birthplace, date of birth, educational background, family relations, or career—so a 400-character encyclopedia-style biography cannot be completed without adding unverified content.

If you wish to continue, please provide any of the following details so I can write a compliant 400-character biography:

- Date and place of birth

- Date of death (if deceased) and place of death

- Educational background (schools, majors, graduation years)

- Professional experience and notable positions

- Major deeds, contributions, or achievements

- Family relations (parents, spouse, children, etc.)

- Other important milestones or publications

Or, if you would prefer a short, objective description based only on the information currently available (without adding any personal details not provided), please let me know and I will draft a non-speculative, itemized description focusing on the work and known historical context. Once you confirm, I will output the complete text.
