Zhang Junsheng

Zhang Junsheng is a astronomy 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 Zhang Junsheng rather than just read about it. In short: Zhang Junsheng (simplified Chinese: 张浚生; traditional Chinese: 張浚生; 1 July 1936 – 19 February 2018) was a Chinese optical engineer, politician, and academic administrator. He spent 25 years as an engineering professor at Zhejiang University and won two national science and technology awards, before entering politics and being sent to Hong Kong in 1985 to prepare for the British colony's return to China.

Key takeaways

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

Reference excerpt

Zhang Junsheng (simplified Chinese: 张浚生; traditional Chinese: 張浚生; 1 July 1936 – 19 February 2018) was a Chinese optical engineer, politician, and academic administrator. He spent 25 years as an engineering professor at Zhejiang University and won two national science and technology awards, before entering politics and being sent to Hong Kong in 1985 to prepare for the British colony's return to China. During his tenure as Beijing's chief spokesman in Hong Kong, he fiercely clashed with Chris Patten, the last British governor in Hong Kong, over the latter's effort to implement political reforms over Beijing's objection. Their public dispute dominated news headlines in Hong Kong. After the transfer of sovereignty over Hong Kong on 1 July 1997, Zhang returned to Zhejiang University to serve as its Party Secretary. He oversaw the school's merger with three other universities and used his Hong Kong connections to raise funds for the university.

Early life and scientific career Zhang was born in 1936 in Changting County, Fujian Province. After graduating from high school in 1954, he was admitted to Zhejiang University (ZJU) in Hangzhou, where he studied optical engineering. At the university he met his future wife Yang Huiyi (杨惠仪), a student from Shanghai. He joined the Chinese Communist Party in 1956, and was hired by the university as a faculty member after his graduation in 1958. In the 1960s, he and his colleagues designed a solar telescope. After the delay caused by the Cultural Revolution, it was put into production in the 1970s and won a National Science and Technology Prize (second class) in 1982. He co-founded the laser program at Zhejiang University in 1973 and won another National Science and Technology Prize (second class) for a solar spectrometer, for which he designed the mechanical components. He was promoted to party secretary of ZJU's Optical Engineering Department in 1978.

Career in Hong Kong In 1983, Zhang was appointed deputy party secretary of Hangzhou, beginning his political career. After the signing of the Sino-British Joint Declaration in 1984, which announced that Great Britain would transfer sovereignty over Hong Kong to China on 1 July 1997, Zhang was assigned to the Hong Kong branch of the Xinhua News Agency, the de facto Chinese embassy in British Hong Kong, to work for the preparation of the handover. He served as deputy director, then director of the Hong Kong branch's publicity department, before being promoted to deputy director and spokesman of the branch in 1988. When Chris Patten, the last British governor of Hong Kong, attempted to implement political reforms prior to the handover, Zhang publicly feuded with Patten, and their dispute dominated news headlines in Hong Kong. Zhang accused Patten of violating the Sino-British agreement and called him "a prostitute who still wanted an arch to be erected to honour her as a chaste woman".

Career in Zhejiang After attending the Hong Kong handover ceremony on 1 July 1997, Zhang returned to Hangzhou. He was appointed Party Secretary of Zhejiang University and oversaw the merger of Hangzhou University, Zhejiang Agricultural University and Zhejiang Medical University into ZJU. He hired the famous writer Jin Yong as president of ZJU's Institute of Humanities, and used his connections to solicit major donations from Hong Kong businesspeople such as Run Run Shaw and Tin Ka Ping. In 2005, a number of alumni and other donors established the "Junsheng Scholarship" in his honour to sponsor students from poor families. As of 2018, the scholarship had a fund of 30 million yuan and had supported more than 2,300 students. He also taught as a part-time professor at Sun Yat-sen University, Communication University of China, in addition to Zhejiang University.

Views on democracy During the Tiananmen Square protests of 1989, Zhang was sympathetic toward the pro-democracy students. He reportedly gave the go-ahead for the Wen Wei Po, Beijing's mouthpiece in Hong Kong, to publish an editorial with only four words: "deep grief" and "bitter hatred" after the government crackdown, but survived the ensuing purge of officials who supported political reform. On the other hand, Zhang was critical of the localism movement in Hong Kong. He said the localist activists were too young to understand the history of the Basic Law, Hong Kong's mini-constitution, and advocated "national education" for students in Hong Kong. He dismissed the Occupy Central with Love and Peace movement in 2014 and criticized its pro-democracy leaders for having "never done anything good for Hong Kong".

Death On 19 February 2018, Zhang died in Hangzhou from cardiac arrest, at the age of 81. Hong Kong chief executive Carrie Lam expressed her sadness and praised Zhang's contributions to the establishment of the Hong Kong special administrative region. Chris Patten also gave his condolences. The South China Morning Post, Hong Kong's major English-language newspaper, published an editorial calling Zhang "a good friend" of Hong Kong who "always had the city’s best interests at heart". Pro-establishment Hong Kong lawmakers Chan Yuen-han and Tam Yiu-chung praised Zhang as "learned", "open to different perspectives", and principled, whereas Cheung Man-kwong, former lawmaker of the Democratic Party, said "Zhang, representing Beijing, made very stern criticisms against the pan-democrats."

Worked examples

Example 1 — a first encounter with Zhang Junsheng

Start with the simplest possible case. Write down what Zhang Junsheng claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Zhang Junsheng 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 Zhang Junsheng 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 Zhang Junsheng

In research
Zhang Junsheng appears in astronomy 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 Zhang Junsheng 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
Zhang Junsheng is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 2018 deaths, Academic staff of Sun Yat-sen University, so understanding it makes those chapters shorter.
In everyday life
Look for Zhang Junsheng 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.
