《黄帝内经·素问·玉机真藏论》
大骨软弱，大肉瘦削，胸中气满，呼吸困难，呼吸时身体振动，为期六个月就要死亡，见了真脏脉，就是预测死期的起点。
大骨枯槁，大肉陷下，胸中气满，喘息不便，其气动形，期六月死，真脏脉见，乃予之期日。
Weakness of the big bones, thinness of the big muscles, fullness of the chest qi, difficulty in breathing, and vibration of the body during breathing. Death will occur within six months. When the true dirty pulse is seen, it is the starting point of predicting the time of death.
