Last night, just as I was about to go to sleep after finishing the update, my grandmother suddenly started coughing up blood. After discussing it with the doctor over the phone for quite a while, we decided to go to the hospital. We called 120 and took an ambulance there. Her condition improved somewhat after she was given hemostatic medication. She spent last night in an isolation ward and was transferred to a regular ward today. Since there are many things to take care of, updates will be paused today. That is all.
PS: Come to think of it, it was really strange. When my grandmother was coughing up blood yesterday, she said she didn't feel unwell anywhere—well, saying that nothing felt wrong while coughing up blood was quite unusual. A lung CT scan after admission showed bronchiectasis and an infection... The problem was, no one knew when it had started. She had been perfectly fine during the day, then it suddenly began when it was time to sleep... So someone really needs to keep an eye on elderly people's health.
