Historically, an old man from Xinjiang visited Chairman Mao in Beijing on foot. Who is he? Did Chairman Mao receive him?

Uncle Cuban, but not on foot. He planned to walk to Beijing several times, but later the local cadres told him that it was too far. He wrote several letters to Chairman Mao, and Chairman Mao personally wrote back to him. Finally, I met Chairman Mao at a national congress (it seems to be 1956) and personally presented Xinjiang specialties. Chairman Mao shook hands with him cordially and took photos as a souvenir.
