From starry sky people's literature publishing house. This poem was first published in the third issue of Creation Quarterly, Volume 1, and was published in March 192 1. 192 1- 1923, Guo Moruo returned from Japan three times. At this time, the climax of the May 4th Movement has passed (192 1~ 1922, China is in a period of warlord melee). Facing the dark reality of the semi-colonial and semi-feudal society, Guo Moruo has a beautiful vision for the new look of the motherland after the May 4th Movement and a desire to achieve social progress through personal efforts. His poetry collection "Starry Sky" created during this period expressed this kind of thought and feeling. For example, "Mourning of the Yellow Sea" wrote: "The waves are turbid, deep, salty, smelly and fishy. The sinister wind and waves have not been quiet for a moment, and the turbulent turbid waves have already dyed my heart. How long will it take me to recover? " However, he was not pessimistic and disappointed, and he continued to explore and pursue tirelessly. He wrote in "Poetry for the Starry Sky": "Ah, twinkling stars! You have some bright red blood stains and some clear tears-how much deep anguish is contained in your poor dim light! " During this period, 192 1, 10 year124 October, the author wrote an imaginative poem "Market in the Sky" (formerly known as "Market in the Sky").
