The early morning sun shone on the ancient streets, and Tou Tou Sun arrived at the medical center early as agreed.In the medical clinic, Ren Xinzheng handed a yellowed book - The Yellow Emperor's Internal Medicine - into her hands, marking the official start of her journey of learning traditional Chinese medicine.However, Mr. Sun frowned as he looked at the ancient book in his hand and admitted that he had been sleepy since he was a child.Ren Xinzheng smiled and shook his head, but he could tell from Sun Tou Tou's slightly stiff posture that she had back pain. He pointed out in an understatement that this was caused by Sun Tou Tou often crossing her legs.Mr. Sun was stunned when he was told this and became very interested in Ren Xinzheng's medical skills.

At the same time, Ren Tianzhen encountered criticism from his Western medicine classmates at his internship place. They believed that Chinese medicine caused trouble but let Western medicine take the blame.However, Ren Tianzhen firmly believes that Chinese and Western medicine have their own strengths. He secretly studies Western medicine knowledge in private, hoping to integrate the two.

At the entrance of the medical center, Toutou Sun began to try to have a consultation, but the door was deserted and no one cared.Ren Tianzhen encouraged his classmate Peng Shiyan to come to the medical clinic to study, and Peng Shiyan readily agreed.After the news spread, Zhao Liquan also expressed his willingness to study traditional Chinese medicine.Although he was not admitted to the graduate school of his choice, in order not to worry his parents, he lied that he had entered a good hospital, but actually chose to study at Ren Xinzheng's Traditional Chinese Medicine Clinic.

One day, after lawyer Yang Xiaohong finished handling the case, her fellow lawyer suddenly collapsed. She dialed 120 in panic.Yang Xiaohong saw TouTou Sun at the door, and her heart ignited hope. She hoped that she could treat some injured patients.At this moment, Peng Shiyan and Zhao Liquan were hanging banners, and Yang Xiaohong's arrival attracted everyone's attention.Her momentum made everyone stop what they were doing, and TouTou Sun quickly stepped forward to say hello, hoping to have a girl to keep him company.

Although the environment of the medical center is simple, Ren Xinzheng believes that it is not easy to have a place to stay.TouTou Sun complained while cleaning, but Ren Xinzheng took the opportunity to teach her.After the classroom was decorated, Ren Xinzheng specially reserved a seat in the first row for Tou Tou Sun.At this time, Tou Tou Sun's best friend Tian Xingxing also rushed over. Although Ren Xinzheng initially did not agree to attend, he agreed after learning that she was a nurse in the emergency department.

The rules before the start of class made everyone wait with bated breath, but the sudden appearance of a woman broke the calm.She claimed that there was a murderer in the tutoring class run by Ren Xinzheng, which shocked everyone present.Ren Xinzheng insisted on attending classes, but Sun Toutou objected to some of his views.

During the break, TouTou Sun deliberately greeted Yang Xiaohong, but Yang Xiaohong ignored him.Ren Tianzhen advised Sun TouTou to talk less and do more, but Sun TouTou teased him as his grandson.Wu Shandao brought the woman to see Ren Xinzheng, but suddenly beat Yang Xiaohong violently. Sun Toutou quickly stepped forward and pulled the two away.It turned out that this woman was Lawyer Kong's wife, and she believed that Yang Xiaohong killed her husband.Song Linglan appeared in time and told her that Yang Xiaohong was pregnant and asked her to pay attention to her health.After the woman was taken away, TouTou Sun persuaded Yang Xiaohong to go to class, but Yang Xiaohong suddenly collapsed.Ren Xinzheng and everyone hurried over, and Boss Sun handed over the silver needle. After Ren Xinzheng's rescue, Yang Xiaohong finally regained her breath.
