I came to Germany for the first time in 2004. Over the years, I visited nearly 60 hospitals across Germany, and became working partners and lifelong friends with hundreds of world-renowned experts. The medical care service level in big cities and small towns in Germany does not vary significantly. All doctors and nurses fully respect and act their professional beliefs, which they always put patients at the highest priority. Famous doctors in big hospitals will not look down on ordinary doctors in small hospitals. They will respect each other. If you go to the hospital for certain things, the staff will always be helpful in a professional way. As long as it is within the scope of his/her profession, as long as it is beneficial to the hospital, as long as it is good to the patient, they will definitely do their best. The German hospital presidents serve all the departments and will respect the opinions of the department heads and they are devoted to making more achievements during their period. Every time I meet with a German hospital president, they would spend at least one hour with me to have a detailed discussion. German hospitals attach great importance to international cooperation. Each hospital organizes international conferences every year, invites world-renowned experts to work regularly in the hospital, and invites key academic leaders to hold health care talks. German hospitals conducted remote consultation more than 20 years ago and many major difficult diseases are completed through international cooperation. They regard cultivating excellent doctors as the eternal cause of the hospital. Thousands of words can be summed up in one sentence: Doctors have professional beliefs.
