In the past nearly half a month, Cao Ling accompanied Grandfather to a large hospital in Paris, where the medical team performed comprehensive checks on Grandfather's health and discovered that his body had accumulated a lot of thick phlegm, particularly filling his lungs.
Last time, shortly after they arrived by plane, Grandfather almost died when that clump of thick phlegm got stuck in his throat.
Back in their home country, various major hospitals and the Military Hospital had conducted examinations and treatments for his condition to no avail, so they had no choice but to seek surgical options abroad.
Unexpectedly, after half a month of examinations, the results showed that surgery was feasible, however, the risk was significant. More importantly, it was a problem with Grandfather's lung function that led to the production of thick phlegm which his body couldn't expel, causing the accumulation to worsen.
