Reference excerpt

The Tan Qindong incident refers to an event on January 10, 2018, in which Tan Qindong (譚秦東), a physician based in Guangzhou, was cross-provincial detained by local police from Liangcheng County, Inner Mongolia, after he published an online post criticizing Hongmao Medicinal Liquor（鴻茅藥酒）company as "toxic".

Background In recent years preceding this incident, local police have frequently detained critics of major local companies across provinces, which has been referred to as "abuse of police power" or "police acting as personal servants of businesses". Against this background, the case has attracted public attention. Tan Qindong is a Chinese physician born in Weinan, Shaanxi. He holds a master's degree in anesthesiology and is a licensed physician in China. He has worked in hospitals and has also served as medical affairs specialist and consultant for pharmaceutical companies. In 2015, he founded a medical technology company.、 Article 221 of the Chinese criminal code is a rarely-used provision that criminalizes claims that could seriously damage a business’s reputation.

Incident In December 2017, Tan Qindong, a physician based in Guangzhou, published an online post criticizing Hongmao Medicinal Liquor, a tonic containing over 60 traditional Chinese medicinal ingredients (in his post titled “China’s Divine Wine ‘Hongmao Medicinal Liquor’, a poison from heaven”). The advertisement for the product claimed it could "boost kidney and stomach functions" and "cure 100 diseases," including bone aches and common colds. After the post, local police from Liangcheng County accused Tan of causing refund losses of approximately 800,000 yuan and severely damaging the company's reputation. They also obtained his registered ID number and phone number from the platform. According to his lawyer, Tan was initially taken from his residence in the Tianhe District of Guangzhou on 10 January 2018 and transported to Shenzhen and then Beijing, before being held in a local detention facility by train and car, accompanied by three police officers and a company executive. Local police requested his detention on 18 January, and the request was approved by the local procuratorate on 25 January, after which he was placed in a detention center. Dr. Tan reportly has experienced psychological distress and suicidal ideation during the detention. Dr. Tan was released on bail after prosecutors found insufficient evidence, though the case remains open and possible compensation may follow if charges are dropped.

Comment An article in Guangming Daily said that “Freedom of speech and the right to exercise oversight are fundamental rights granted to citizens by the Constitution” to this incident. Wang Yong, a professor of commercial law at the China University of Political Science and Law in Beijing said that “This is a fairly typical instance of the public security authorities intervening in a civil dispute; it’s an overreach of power” in an interview.

Worked examples

Example 1 — a first encounter with Tan Qindong incident

Start with the simplest possible case. Write down what Tan Qindong incident 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 Tan Qindong incident 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 Tan Qindong incident 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 Tan Qindong incident

In research: Tan Qindong incident 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 Tan Qindong incident 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: Tan Qindong incident is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2018 controversies, 2018 in Guangzhou, Criticisms of companies, so understanding it makes those chapters shorter.
In everyday life: Look for Tan Qindong incident 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.
