《黄帝内经·素问·六元正纪大论》
终之气，主气为太阳寒水，客气为少阳相火，由于少阳之烈火主令，阳气大化，蛰虫出现，流水不得结冰，地中阳气发泄，草类生长，人们也感到舒适，其发病则为温病、疫疠。
终之气，畏火司令，阳乃大化，蛰虫出见，流水不冰，地气大发，草乃生，人乃舒，其病温、厉。
The Final Qi: The dominant Qi is Taiyang cold water while the secondary Qi is Shaoyang mutual fire. Because of the forcefulness of the Shaoyang fire, Yang Qi greatly transforms.
