It's funny, but having lived all these years in Germany I've gotten used to the sanatariums that are an integral part of healthcare system here. After major surgery, doctors often write out a medical certificate for the patient to recover in a public or private sanatarium. Even sanatariums in neighboring countries such as Austria and the Czech Republic are covered by German health insurers.
說來好笑，在德國多年，我已習慣了醫療體系中附屬的「療養」部分，它屬於一整套流程作業，通常動完大手術的病人出院後，醫師便會開出證明，憑單可到風景優美的公、私立療養院調養身體（甚至國外的療養院也承認，如鄰近的奧地利、捷克等）。
