What solar terms does Summer Dream Festival correspond to?

"On a summer dream day, everything is beautiful" means that in the first month of summer, everything is in full bloom. From Lian's "Eight Notes on Respect for Life": On the day, heaven and earth began to merge, and everything was beautiful. "In the days of Xia Meng, everything is beautiful." The ancients believed that the weather would be more suitable for crop growth from the beginning of long summer.

Xia Meng: The ancients divided the four seasons of the lunar calendar into "Meng", "Zhong" and "Ji" in turn, with "Meng" as the first month, "Xia Meng" as the first month of summer, that is, April of the lunar calendar, and "Summer Dream Day" as the long summer. People regard "Xia Meng" as the season when everything is thriving and the harvest is coming.
