Deng Guang is a real person. He was the younger brother of Deng Youde of the Kuomintang Information Bureau at that time. Deng Youde has three younger brothers in Yan 'an, one of whom is Deng Guang. Deng Youde was the deputy head of the Yan 'an delegation of Chinese and foreign journalists 1944, while Deng Guang was a water conservancy scientist in Yan 'an period, and recorded a short conversation between the two brothers in Ode to Yan 'an.

Deng Guang: "Chinese and foreign journalists! I came to Yan 'an voluntarily; Because of my distant brother's special status, I was rescued in Yan 'an. However, when your familiar Duke Zhou knew about it, he explained the situation to President Mao Zedong, and I was fine. I study water conservancy. General Wang lacked talents in this field when he reclaimed land in Nanniwan, so I volunteered to come here again. " He pointed to the mud on his leg. "Look, this is the sign that I take the lead in diverting water!" "

Deng Youde: "Brother, what you said must not be true!" " "

Deng Guang: "No! All the truth. I will never go back to Chongqing again, because China's hope lies in Yan 'an! " "

So Deng Guang does exist, but it has become a small wave in the long river of history.
