"Lianxie"（恋邪） means healthy qi turns into pathogenic qi

and the two are integrated into one

and the damage of original "pathogen" is exerted

thus making the disease difficult to heal. The "lianxie" of sore face makes the healing of the sore surface reversed

which is mainly related to the irregular use of Shengji Ointment（生肌油膏）. Through the theoretical exploration of "lianxie" of sore face and the rational application of Shengji Ointment

combined with the ancient books and clinical practice

the causes of "lianxie" of sore face were analyzed

and it was pointed out that the premature

excessive and single application of Shengji Ointment should be prevented

which provides ideas for the rational application of Shengji Ointment in traditional Chinese medicine surgery.
