A friend I haven't seen for a long time came to Beijing to see me. I deliberately asked for leave to take him out to play, but I didn't expect to have a good time. But when I came back from the scenic spot, my friend was ill. At first, he said he was dizzy, and we didn't care. As a result, he fell ill as soon as he got home. I immediately took him to Beijing Millennium Monument Hospital affiliated to Capital Medical University for medical treatment, because it was night and there was only an emergency. When I went there, I queued up for registration, medical treatment and laboratory tests. My friend wants a blood test and a urine test. I thought it would be detailed.
