Evil qi blocks the lungs, which can cause chest pain. The evil heat is abundant, burns the lungs, and hemoptysis can be seen. If the evil qi is excessive, the good will not prevail over the evil, the evil qi will enter the inside, and the blood will be transmitted inside, and even the evil heat will be invaginated, and the pericardium will be transmitted backwards, which can lead to the exhaustion of true yin and yangQi deficiencyTake off.
