To celebrate the 90th anniversary of CPC, retired cadre Lin Yuhong of Norinco dedicated a written scroll titled "Constitutions of CPC in History" to CPC as a birthday present. Having spent 160 days and nights on this 108-meter long scroll, which is all written with Xiao Kai (a writing style in Chinese calligraphy) and includes about 150,000 words, Lin Yuhong, a Party member for 55 years, expressed his sincerity and loyalty to the Party through the scroll.

This masterpiece contains full text of all CPC Constitutions from the "1st Party congress" to the "17th". Recording the historical vicissitudes of the Party, these texts re-present the trajectory of CPC from infancy to maturity from a peculiar perspective.

To write this long scroll, this eightyish man had to go through unimaginable difficulties and challenges. For nearly half a year, comrade Li Yuhong challenged himself to keep writing every day with strong will despite his blurred vision, stiff wrist, shaking hand and physical discomfort. Eventually he completed this masterpiece and fulfilled his wish.
