During the Taihe period of Cao Wei, there was a half-hearted doctor named Hu Youcai wandering around the city of Xuchang. His medical skills were rudimentary and he had not even read the Huangdi Neijing in full. He relied on his clever mouth and a bit of luck to make a living by setting up a street stall. However, as fate would have it, he accidentally used a ridiculous folk remedy to "cure" the old asthma of Wang Yuankui, a wealthy businessman in Xuchang. From then on, he became famous and became a "miracle doctor" among the people.
For a time, dignitaries and ordinary people flocked in, and Hu Youcai had to walk cautiously on the tightrope of lies. He relied on guessing when prescribing medicine and guessing his pulse, but he always managed to get the right answer and avert danger into safety. As his reputation grew, he gradually became involved in the maelstrom of intrigues and grudges in Xuchang City, and even had a subtle connection with the court of Cao Wei.
This novel uses a humorous tone to tell the story of how a charlatan struggled to survive in troubled times, and finally found his own "medical way" between lies and truth, money and conscience.
