One day in 2023, his grandson who was studying in college in Sichuan and the United States suddenly came home and told Li Yi that he had a boyfriend, which reminded Li Yi of a past event in his youth. In 1982, he went with an inspection team from the Department of Architecture of Peking University to a Dai village in Yunnan to investigate the local stilt house architecture. By chance, he met Zhang Ningqiu, a painting major at Central America. The two met, got to know each other, and then parted in just one day and one night, but the ambiguous feelings and soul-to-soul sympathy were so wonderful. One foot was the space left for the relationship between the two, and it was also the last restraint of both parties.
Intention: "Zhang Ningqiu, I still remember the hot night of September 18, 1982."
