The 27th translation exercise(Test 19)

The original :

中国是率先拥有医药文化的几个国家之一。与西医相比，中医的治疗方法完全不同。经过5000年的发展，中医已经对医药学（medical science）、理论、诊断方法、处方等方面形成了一个深刻且全面的理解。中医医生可以没有任何辅助设备，只通过一次体检就能够治愈无数病人，这实在是一个奇迹。四诊法包括望、闻、问、切（observation,auscultation and olfaction,interrogation, pulse-taking and palpation）。其中，“望”是指医生直接从病人的外貌来获悉病人的情况。由于外部面貌与内部器官是相对应的，当内部器官出现问题时，会直接地显现外部皮肤上。

My translation :

China was one of the first countries having a medical culture. In comparison with Western medicine , the traditional Chinese medicine takes a far more different approach. With a history of 5000 years, it has formed a deep and immense knowledge of medical science, theories, diagnostic methods, prescriptions, etc. It is a wonder that the doctors of traditional Chinese medicine could cure countless patients without any assistant apparatus but only through a physical examination. The four methods of diagnosis consist of observation, auscultation and olfaction, interrogation, pulse-taking and palpation. Among these methods, observation indicates that doctors directly watch the outward appearance to know a patient's condition. As the exterior and interior closely link to each other, when the inner organ runs wrong, it will be reflected through the exterior  skin.
