道家学派代表人物孙思邈的大医精诚

高明见，南北朝至隋唐间著名道士、医药学家，于阴阳、推步（天文历法）、医药无不善。孙思邈所著之《备急千金要方》第一卷提出“大医精诚”的思想，是论述医德的一篇极重要文献，为习医者所必读。其中认为大医必须具备两个品质，第一是精，即要求医者要有精湛的医术，认为medical practice is a "most precise and subtle art," those who study medicine must "extensively learn the sources of medicine, diligently cultivate without rest."第二是诚，即要求医者要有高尚的品德修养，以"feeling the suffering of others as if it were one's own" compassionate heart, inspiring a great sense of benevolence and empathy, ultimately vowing to alleviate the suffering of all sentient beings. Without seeking personal fame or wealth, they should not be swayed by pride in their abilities or greed for material gain. With such noble medical ethics, he was revered as the "Medicine King" by later generations.

The biography in the Old Tang Book states: Sun Simiao was born in Huayuan County, Jingzhao (now Yecheng County in Shaanxi Province). He began his studies at seven years old and memorized over 1,000 characters every day. By age twenty-five he had mastered discussions on Zhuangzi and Laozi as well as other philosophical works; he also excelled at Buddhist scriptures. When Duke Liuqiu saw him, he exclaimed: “This child is truly extraordinary! It’s just that his talent exceeds his opportunities.” During Emperor Wen's reign of Sui Dynasty when Sun Simiao declined an appointment as National University Professor due to illness.

As recorded in The Old Tang Book: “Sun Simiao once said to his close friends: 'In fifty more years there will be a sage who will emerge; I shall then assist him in benefiting humanity.' When Emperor Taizong ascended to power and summoned him to court with great respect for his youthfulness—Sun Simiao looked so young—Emperor Taizong praised him saying: 'It is clear that one who possesses knowledge is truly deserving of respect; are not Song Linwen and Meng Qu from Lu Zhouni talking about something real?'" In Xianqing Year Four during Emperor Gaozong's reign Sun Simiao politely declined an appointment as Censor-in-Chief again before returning home whereupon he was granted a fine horse by imperial order.

During this time notable scholars like Song Lingwen , Meng Qu , Lu Zhouni treated him with deference worthy of their teacher . However , The Old Tang Book contains contradictory accounts which have led to centuries-long debate regarding Sun Simiao's true lifespan ! According to these records : Sun Simiao claimed birth year was Kaihuang Year Sinousa (541 AD) but since Kaihuang Years only spanned from 581-600 AD with no Sinousa Year present — instead being replaced by Daxing Seven Year (541 AD) under Western Wei rule - this would mean Son Siemio could only travel back through time meet Duke Liuqiu ! Furthermore , according to these same records , when Empress Wu Zetian ordered historians Weicheng et al. inquire into historical events across five dynasties while visiting Son Siemio whose memories seemed like having witnessed them firsthand — implying Son Siemio lived during Southern Dynasties West Wei period i.e., 541 AD . Lastly upon death at Eternal Peace Period Two Hundred Twenty-Eight-Year mark — equivalent 682 A.D., Son Siemio left instructions for simple burial without any funerary objects nor sacrifices ; after a month following funeral appearance remained unchanged .

Throughout history various honorific titles were bestowed upon him including:
