In the lonely situation of Hu Ming's later years, a peddler who sold hemp cakes actually became his friend, bringing him a little unexpected comfort and happiness.
The peddler's name is Yuan Gang, he makes cakes and sells cakes, but also loves to read a little book, likes to discuss the British and American political systems with people, in the end, which is better, the British and American political systems? He tended to worship the United States, but theoretically he did not understand it and never received a satisfactory answer. So he hastily wrote a long letter and asked the university scholar Hu Ming for advice. This was in October 1950.

When Hu Ming received this letter, he knew that he was a peddler who sold sesame cakes, and that he could study diligently and in his spare time, and his spirit was admirable; he asked Dr. Hu's most enthusiastic Anglo-American political issues, and he felt very happy, so he wrote a reply in his own handwriting. The letter said: "I am ashamed that the question you have raised is too great, and I cannot give you an answer that I can satisfy myself, and I can only say that there is no great difference between the British system and the American system that you are talking about." The story of the one you wrote about, Truman, didn't take a man with him: the same story that Churchill didn't take with him when he left 12 Downing Street in 1946.
"I can also say that in our country, there is a cake seller who carries a lead-skin bucket on the street every day to sell sesame cakes, rain or shine, and the scorching sun is even less concerned about it, but he is also willing to sneak around, care about the national plan, and care about the long-term peace and stability of Britain and the United States. If there is anything I can do you a little favor, such as giving away books that you can't find, I will definitely be willing to do . . . . . . Since then, the peddler Yuan Gang has become the "my friend" of Dr. Hu Shi, one day, Hu Ming invited Yuan Gang to the Central Research Institute in Nangang to be a guest, Yuan Gang opened a hand towel bag he brought, which contained 10 sesame cakes, yellow and brilliant, emitting the fragrance of freshly baked sesame seeds, and held it in front of Hu Ming. Hu Ming took the sesame cake, smiled and picked up a bento to eat, chewing it creaking, and his face showed the joy he had only seen in recent years.
