A few hours later, the operation was over. It was several hours before the operation was over. Compare and talk about the differences.

We should have said the last sentence. In these two sentences, there is a distinction between "le" and "Cai". The patient in front is relatively calm and seems to be telling.

Now she has been discharged from the hospital and is recovering. She is always complaining about stomachache these days. I'm worried about postoperative intestinal adhesion. I wish my daughter a smooth ride! She suffered too much when she was 3 years old. God, please don't give her all the bad things. She is so young, can you bear it? Give it all to me, give it to me, let me share it for her, please!
