Episode 4 recap: Li Chang Sheng taught Bai Shi Zhou about social intricacies.

Ma Chong Feng accompanied Bai Shi Zhou to the ancestral hall to familiarize him with the environment. Wang Ya Nan mentioned that it was Bai Doctor's first time in such a place and hoped he would seriously consider the appointment as the health committee member. Being a newcomer, she expressed concerns about entrusting the safety and well-being of the people to him. Bai Shi Zhou asked if Ya Nan doubted his expertise. Ma Chong Feng assured him that he had good judgment. Wang Ya Nan had no choice but to hope that Li Chang Sheng could come as soon as possible.

Li Chang Sheng couldn't figure out why Da Wei pretended to be sick. Da Wei had been pretending to be sick while his wife constantly caused trouble, and Li Chang Sheng's mind was in chaos, completely unaware of Da Wei's act. The neighbor suggested that he could take this opportunity to retire, but Li Chang Sheng believed that he couldn't retire just because his skills were inferior to others. The neighbor pointed out that he could use this opportunity to assess and observe the young people. If he proved capable, he could continue working; otherwise, someone would surely ask him for help. After learning about Li Chang Sheng being bullied by Bai Shi Zhou, Xiao Ze immediately decided to find him and settle the score, so he gathered two people and rushed over.

At that moment, Bai Shi Zhou was tidying up the office and had to clean the dust himself. Xiao Ze arrived at the ancestral hall and accused Bai Shi Zhou of bullying others. Just as they were about to take action, a man came forward and tried to dissuade them. He explained that the reason Dr. Li had been here for so long was because he had been practicing medicine for generations and had taken care of so many people. If Bai Shi Zhou wanted to earn respect, he should work hard and strive to do more good for everyone.

Bai Shi Zhou was taken aback by the situation and could only nod in confusion. In the morning, when Bai Shi Zhou woke up and saw Wang Ya Nan, she asked if he had slept well because she noticed his light was on until late last night. She intended to give him some calming incense from Li Chang Sheng but he expressed fear that he wouldn't be able to wake up after using it. Wang Ya Nan told him that his methods wouldn't work and suggested that he should focus on improving the medical environment there. Bai Shi Zhou mentioned that relying solely on his memory was prone to mistakes.

Li Chang Sheng openly admitted that if it weren't for Bai Shi Zhou holding him back, he would have fought for justice. The neighbor suggested that he should take a good rest, go fishing, and tend to flowers. However, Li Chang Sheng said he couldn't get used to such a lifestyle. Wang Ya Nan showed Liang Manager's contract, but they faced resistance from the accountant. Li Chang Sheng criticized the contract for being unfair and claimed that the standards set by others were unjust to the villagers. Wang Ya Nan argued that it could help promote their brand, so the contract could still be signed based on that aspect.

Wang Ya Nan brought tea to see Accountant Wu, who said he didn't buy into their approach. Wang Ya Nan mentioned that they should seize the opportunity of the internet era because they don't have the upper hand in negotiations. They don't have the right to make demands because there are no other platforms willing to collaborate with them. Accountant Wu stated that she's not from this place, so the unfair clauses in the agreement should be removed.

The villagers find it troublesome to undergo tests every time they visit Bai Shi Zhou. Mr. Meng's condition was critical, so they hurriedly went to find Li Chang Sheng but couldn't locate him. They had to find Bai Shi Zhou instead. When they arrived at Mr. Meng's house, Dr. Li was already there, stating that Mr. Meng's condition was dangerous and they should call for emergency help. Li Chang Sheng bluntly stated that at this age, moving Mr. Meng to a hospital and performing surgery is simply not feasible. He can't solely rely on medical knowledge without considering the patient's actual situation.

Li Chang Sheng mentioned that every household in Xiancao Village is different, and his efforts to jump around haven't accomplished much. Therefore, he should learn about social intricacies. Accountant Wu took the official seal home to prevent Wang Ya Nan from stamping it. Bai Shi Zhou returned to the ancestral hall, but no one opened the door, so he had to rest on the side. When Wang Ya Nan opened the door and saw him, she immediately asked what was happening and noticed his legs, suggesting that he should have cleaned up beforehand as a doctor. Bai Shi Zhou told her she didn't need to worry about it.

Da Wei's wife called Ma Chong Feng, but the call was hung up, so she immediately declared that she would go and settle the score with him. Fan Lili, who didn't benefit from the situation, led a group of square dance ladies to cause trouble at the ancestral hall. They explicitly revealed to Li Chang Sheng how they deceived him regarding Bai Shi Zhou. Upon learning this, Li Chang Sheng rushed over immediately. Fortunately, with the presence of Wang Ya Nan, the situation didn't become too awkward for Bai Shi Zhou. In the end, it was Li Chang Sheng who spoke up and stated that Bai Shi Zhou is an excellent doctor, which diffused the tension.

Wang Ya Nan told Bai Shi Zhou that trust is gradually built, and Dr. Li gave him a second chance by vouching for him today. Li Chang Sheng returned home feeling perplexed because by guaranteeing for Bai Shi Zhou today, if Bai Shi Zhou truly fails one day, it would be his own reputation at stake.
