In July in Qi'an, the air was filled with orange-flavored soda. The scorching sun was roasting the earth with unbridled poison. The flowers and plants hung their heads and everything seemed to have lost all life. Luo Qiran took the No. 19 Bus all the way south. Today is a weekend. Luo Qiran is going to work as a volunteer at a sunflower planting base in the southernmost part of Li'an. There are endless sunflowers there. This is the flowering season. Luo Qiran was born and raised in the north. After graduating from Northern University, he decided to come here despite his father's objections. This city of Li'an, known as the "Flower City", is no colder and drier than the air in the north. On the contrary, the air is often filled with the fragrance of various flowers. Therefore, in this month every year, hundreds of tourists from all over the world come to see the blooming flowers of Li'an. Luo Qiran has lived in this city for two years. He works as an editor in a magazine during the weekdays and volunteers at the sunflower planting base on weekends to collect materials, and he lives a comfortable life.
