After working for more than 3 years in an enterprise in Xinmi City, a worker named Zhang Haichao was diagnosed by many hospitals with pneumoconiosis, but the enterprise refused to provide him with relevant information. After filing multiple complaints with the higher authorities, he was finally able to get the chance to have an official evaluation. However, Zhengzhou Occupational Disease Prevention Institute gave him a diagnosis of "tuberculosis". In order to seek the truth, the 28-year-old went to the First Affiliated Hospital of Zhengzhou University and insisted on having a thoracotomy to examine his lungs despite the doctor's advice against it. With this act of desperation, he exposed the lie.
