Chinese man coughed endlessly for two years

A Chinese man coughed endlessly for two years. Doctors could do nothing, and it turned out he had a pepper stuck in his lung. The man thought he had cancer, and everything the doctors did didn't help. Eventually, a scan revealed a tumor. After the operation, it turned out it was just a piece of chili. When the Chinese man learned about it, he remembered that he choked on food and coughed violently two years ago.
