Lixia is the seventh solar term in the twenty-four solar terms, and the first solar term in summer, also known as "the end of spring". Li Xia said goodbye to spring and the beginning of summer. Spring is born, summer is long, autumn is harvested, winter is hidden, and when the beginning of summer, all things flourish. Due to my country's vast territory and large north-south span, the natural rhythms vary from place to place. During the beginning of summer, only the area south of the line from Fuzhou to Nanling in my country has entered the true sense of summer; while some areas in the northeast and northwest have just had the breath of spring.
