Reference excerpt

Li Yishan wenji (simplified Chinese: 李义山文集; traditional Chinese: 李義山文集; Wade–Giles: Li I-shan wen-chi; "Literary Collection of Li Yishan") refers to the collected works of Li Yishan, i.e. the literary anthology of the famous late Tang dynasty Chinese poet Li Shangyin (李商隱) (813–858), whose courtesy name was Yishan. It is a key source for his profound poetry and prose, often found in compilations like the Sibu congkan (Four Branches of Literature). His poems are collected under the title Yuxi sheng shizhu 玉谿生诗注 in the same collectaneum Sibu congkan, there is also a Qing time commentary under the titel Yuxi Sheng shiji jianzhu 玉谿生诗集笺注 (Shanghai guji chubanshe, 1979).

Bibliography The Hanyu da zidian (HYDZD) uses the edition of the Sibu congkan (SBCK) and the following five editions and comments, all from the time of the Qing dynasty:

Zhu Heling 朱鹤龄: Li Yishan shizhu 李义山诗注 (Siku quanshu 四库全书) Ji Yun dianlun 纪昀点论: Li Yishan shiji 李义山诗集 (Jingyantang shizhong 镜烟堂十种) Qian Zhenlun 钱振伦, Qian Zhenchang zhu 钱振常注: Fannan wenji bubian 樊南文集补编>> (Sibu beiyao 四部备要) Feng Hao 冯浩: Fannan wenji xiangzhu 樊南文集详注 (Sibu beiyao 四部备要) Xu Shugu 徐树谷, Xu Jiong 徐炯: Li Yishan wenji jianzhu 李义山文集笺注 (Chizaotang Siku quanshu huiyao 摛藻堂四库全书荟要)

Worked examples

Example 1 — a first encounter with Li Yishan wenji

Start with the simplest possible case. Write down what Li Yishan wenji 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 Li Yishan wenji 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 Li Yishan wenji 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 Li Yishan wenji

In research: Li Yishan wenji 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 Li Yishan wenji 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: Li Yishan wenji is common in secondary-school and first-year university syllabi. It links to neighbouring topics China stubs, Chinese literature, Geography book stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Li Yishan wenji 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.
