Sun Fan had been away from home for five years. At the train station on his way back home, he met an old man who suffered a sudden myocardial infarction.
When he was about to lend a helping hand, the director of Minjiang Cardiac Surgery stepped in.
Due to a diagnostic error, the old man was given nitroglycerin, which worsened his condition.
At the critical moment, Sun Fan used traditional Chinese medicine and acupuncture to revive the old man who fell into a coma.
The old man in a high position was suspicious of Sun Fan's sudden appearance.
After investigation, it was discovered that Sun Fan was the grandson of a national expert in traditional Chinese medicine in Daxia, and was also the fiancé of his granddaughter.
