Hu Sihui

Hu Sihui is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hu Sihui rather than just read about it. In short: Hu Sihui (Chinese: 忽思慧, 和斯輝, 忽斯慧, also Hu Zheng Qi Huei; active nr. 1314–1330) was a Chinese court therapist and dietitian during Yuan dynasty. He is known for his book Yinshan zhengyao (Dietary Principles), that became a classic in Chinese medicine and Chinese cuisine.

Key takeaways

  • Hu Sihui belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hu Sihui to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hu Sihui from memory before moving on to harder problems.

Reference excerpt

Hu Sihui (Chinese: 忽思慧, 和斯輝, 忽斯慧, also Hu Zheng Qi Huei; active nr. 1314–1330) was a Chinese court therapist and dietitian during Yuan dynasty. He is known for his book Yinshan zhengyao (Dietary Principles), that became a classic in Chinese medicine and Chinese cuisine. He was the first to empirically discover and clearly describe deficiency diseases.

Biography The career of Hu Sihui, as he states in preface to his book, was in the reign of Buyantu Khan in Yenyu years (1314—1320). His ethnicity is unclear. He has been credited as of Mongol descent by some East Asian scholars, while Western scholars have pointed out his Turkic descent, his book being "far too comfortable with Turkic and a larger Islamic culture." He was an official in Xuanhui Yuan (the Ministry of Court Supplies and Provisions), around 1315 Hu Sihui initially emerged as the therapist of Empress Dowager, soon also became the therapist of the acting Empress, and later received the rank of the chief Imperial therapist and became responsible for dietary planning of the numerous members of the Emperor's family. As tradition has it, Buyantu Khan, after several years of expeditions and irregular life, was overstrained and suffered acute pain in his kidneys. The vegetable soup prescribed by Hu Sihui cured the pains in 3 months, and one of Emperor's spouses became pregnant. The Emperor grandly awarded Hu Sihui as the cause of this "double joy". In 1330, Hu Sihui, no longer busy with the Emperor and his harem, completed and presented to the Court his book Yinshan zhengyao, summarising his experiences as court dietitian. The main idea of his work was that people preparing food for the Emperor are directly responsible for efficiency of the State, as a monarch may get sick from improper eating, and lose the ability to properly manage state affairs effectively.

Legacy Hu Sihui's book was widely accepted in Later Yuan, but won even wider influence after the fall of Yuan. Ming Dynasty, after occupying Beijing in 1368, started to combine Chinese cuisine from other regions with the cosmopolitan cuisine of Yuan court. Jingtai Emperor of Ming (ruled 1449—1457) personally wrote a preface to an edition of Yinshan zhengyao. As a culinary encyclopedia, this book made some regional recipes accepted as a part of the national cuisine of the whole of China. For example, it is this book that contained a recipe for roast duck that could be a predecessor of the widely known Beijing duck.

Worked examples

Example 1 — a first encounter with Hu Sihui

Start with the simplest possible case. Write down what Hu Sihui claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hu Sihui before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hu Sihui ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hu Sihui

In research
Hu Sihui appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hu Sihui in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hu Sihui is common in secondary-school and first-year university syllabi. It links to neighbouring topics 14th-century Chinese medical doctors, Dietitians, Turkic peoples, so understanding it makes those chapters shorter.
In everyday life
Look for Hu Sihui outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
