Introduction to Mao Zedong’s inscription stele: The people of Dalian are already familiar with the three words "Bangchui Island" written by Chairman Mao. However, there are different opinions on the origin of these three words: some said that someone selected and combined them from the words written by Chairman Mao; some said that Chairman Mao was asked to inscribe the Bangchui Island Hotel, and Chairman Mao wrote With a wave of his hand, he wrote the words "Bangchui Island" but not the word "hotel". Some people inferred from this that Chairman Mao had been to Dalian during his lifetime, and the words were left behind by the old man when he was in Dalian.
