(Zhang) Pu was fond of learning when he was young. What you read must be cashed by hand. The banknotes have been read aloud. When they are passed, they are burned and banknotes are printed again. This has been done since six or seven years. When the right hand holds the tube, the palms of the fingers become cocoons. In winter, my hands are chapped, and I get wet every day. Later, he was named "Shu Zhi Zhai" as "Qi Lu"... Pu was quick in poetry and prose, and he was able to search from all directions without drafting any drafts.
