Guess: Which of the following activities did the ancients often do in the solar terms of mango cultivation?

It is an ancient folk custom to send flowers to the gods during the awning season. It is believed that the seeds of awn have passed, the flowers begin to wither and the flower god abdicates. Therefore, people often hold a ceremony to worship the flower god on Mangzi Day, and at the same time express their gratitude to the flower god, hoping to meet again next year. On that day, people will set up offerings, burn incense and offer sacrifices, and bid farewell to the flower gods.

Cao Xueqin wrote in the 27th chapter of A Dream of Red Mansions: "Those girls, either weaving sedan-chair horses with petals and willow branches or folding them into dry buildings with brocade yarn, are all tied with colored threads. These things are tied to every tree and every flower. Embroidered ribbons are flying in the garden and flowers are in full bloom. According to the old saying, after the ear planting festival, when the fragrant flower shakes off and the flower god abdicates, the world will solemnly bid her farewell to show its gratitude.

"The next day is April 26th. It turns out that this day is not the end of the ear festival. Ancient custom: On the day of transplanting rice, all kinds of gifts should be arranged to worship the flower god. It is said that once the planting of flowers is over, it will be summer, all the flowers will be unloaded, and the flower god will abdicate and have to say goodbye. However, this custom is popular in boudoir, so people in Grand View Garden get up early. "
