1September, 938, Xu Teli went to Yan 'an to attend the Sixth Plenary Session of the Sixth Central Committee of the Communist Party of China, passing through Xiangtan, and stayed in an oil and salt shop for one night. At that time, several young shop assistants sat in front of Mr. Xu and asked him to talk about revolutionary truth. Xu talked about guerrilla warfare behind enemy lines from the bright future of War of Resistance against Japanese Aggression, and talked about social life from state affairs until late at night. Encouraged by this, the young shop assistants unanimously asked Lao Xu to write an inscription as a souvenir, and Lao Xu promised to write it and send it. In February of the following year (12), Lao Xu personally wrote a couplet: "I often read books about China; Nothing is good for body and mind. " And send the banner with this link to Wang, a young worker in the shop. The first book is Mr. Zheng, and the second book is Brother Xu Teli. Wang regards his couplets and banners as good words to inspire his progress. It is of great educational significance and embodies the great concern and ardent expectation of proletarian revolutionaries for young people. It will be immortal in the history of China couplets.
