I remembered 4 years ago when I was experiencing my first week at hospital as a medical student, I started watching your videos. I was so impressed by your great videos and I watched them one after another that I forgot to look at the channel's name ! I lost track of your channel ....until today ..... Today I found your channel again, but this time I'm watching them as a medical doctor. (I graduated 2 weeks ago ) Thanks again Doctor Bolin 🌹🌸
