The gentle breeze warms September in the north. Hostas bloomed all over the campus, with green leaves and lavender petals decorating the entire space. On the long and narrow tree-lined path, pedestrians walk side by side without interfering with each other. The moisture in the air and the scent of flowers are hard to associate with the ruggedness and wildness of northerners. This is a university in the north, but it is also a garden nestled in the snowy countryside of the north - Qingtian Agricultural University.
