Li Yu (Southern Tang)

Li Yu (Southern Tang) 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 Li Yu (Southern Tang) rather than just read about it. In short: Li Yu (Chinese: 李煜; c.15 August 937 – 13 August 978), before 961 known as Li Congjia (李從嘉), also known as Li Houzhu (李後主; literally "Last Ruler Li" or "Last Lord Li"), was the third ruler of the Southern Tang state during the Five Dynasties and Ten Kingdoms period. He reigned from 961 until 976, when his state was conquered by the Northern Song dynasty.

Reference excerpt

Li Yu (Chinese: 李煜; c.15 August 937 – 13 August 978), before 961 known as Li Congjia (李從嘉), also known as Li Houzhu (李後主; literally "Last Ruler Li" or "Last Lord Li"), was the third ruler of the Southern Tang state during the Five Dynasties and Ten Kingdoms period. He reigned from 961 until 976, when his state was conquered by the Northern Song dynasty. Taken captive to the Song capital Bianjing, Li Yu was given the title Marquis of Disobedience (違命侯), reflecting Emperor Taizu of Song’s resentment over Li’s delayed surrender. In 978 he was executed by poisoning on the orders of Emperor Taizong of Song. Li Yu is regarded as an ineffective ruler but an accomplished artist, especially renowned for his ci poetry. His early poetry depicts courtly pleasures and romantic love, while his later poetry expresses profound grief over the loss of his kingdom.

Family Parents

Father: Li Jing Mother: Empress Guangmu (光穆皇后; d.965) of the Zhong clan (鍾氏) Consort and their respective issue(s)

Empress Zhaohui, of the Zhou clan (昭惠國后 周氏), personal name Ehuang (娥皇) Li Zhongyu, Duke Qingyuan (清源郡公 李仲寓; 958–994), 1st son Li Zhongxuan, Prince Huaixian (岐懷獻王 李仲宣; 961–964), 2nd son Empress Zhou the younger, of the Zhou clan (小周后 周氏), sister of Empress Zhaohui Baoyi, of the Huang clan (保儀黃氏) Gongren, of the Bao clan (宮人喬氏) Gongren, of the Zang clan (宮人臧氏)

Early life In the same Chinese year Li Congjia was born, his grandfather Xu Zhigao, also known as Xu Gao (Li Bian) founded the state Qi (齊), renaming it Tang (known as the Southern Tang) 2 years later. When Li Congjia was 6, his father Li Jing became the next Southern Tang emperor. With Li Jing naming his younger brother Li Jingsui his heir apparent, his sixth eldest son Li Congjia seemed unlikely to ever succeed the throne. However, many of Li Congjia's brothers died very young, and after the death of the second eldest brother Li Hongmao (李弘茂) in 951, Li Congjia all of a sudden found himself right behind Li Hongji — the eldest brother — and uncle Li Jingsui in the succession line. Li Hongji, a withdrawn and troubled young man, resented his crown prince uncle, whom he saw as a political enemy standing in his way. He also disliked his younger brother Li Congjia, even though they shared the same biological mother, Empress Zhong. Fearing the possible results of this family enmity, Li Congjia tried hard to be inconspicuous and focused on the arts, including poetry, painting and music. He loved reading, a passion encouraged by his father, also an acclaimed poet. At the age of 17, Li Congjia married Zhou Ehuang, chancellor Zhou Zong's daughter and a year his senior. Lady Zhou was not only highly educated but also multi-talented in music and the arts and the young couple enjoyed a very intimate relationship.

Accession to the throne In 955, a year after Li Congjia's marriage, Southern Tang was invaded by Later Zhou. The resistance war did not end until spring 958, after Li Jing ceded all prefectures north of the Yangtze River to his powerful northern neighbor. Li Jing also relinquished all imperial trappings, degrading his own title from emperor to king (國主). The national humiliation was soon followed by familial tragedy: later that year Li Hongji poisoned uncle Li Jingsui to death, which was followed by his own death a few months later, allegedly hastened by many encounters with Li Jingsui's vengeful ghost. Not long after Li Hongji's death in 959, Li Congjia was given the post of royal secretary (尚書令) so that he could familiarize himself of governmental affairs. However, despite being the king's eldest surviving son, a few ministers considered him too dissolute and weak for the crown prince position, including Zhong Mo, who pleaded to have Li Congjia's younger brother Li Congshan chosen instead. Li Jing found Zhong's suggestion offensive and demoted him. Suffering from poor health, Li Jing decided to transfer all responsibilities to his successor. He named Li Congjia the crown prince in spring 961 to take over in the capital Jinling (金陵; modern Nanjing, Jiangsu) while he retired to the southern city of Hongzhou (洪州; modern Nanchang, Jiangxi). A few months later he died, and Li Congjia officially succeeded the throne, not without a last-second effort by Li Congshan to challenge him. By then Zhong Mo had also died, so Li Congshan asked chancellor Xu You to bring Li Jing's last will to him. Xu refused and confided in Li Congjia of Li Congshan's intentions. Li Congjia — changing his name to Li Yu — did not punish his younger brother other than a slight demotion.

As Southern Tang ruler

Appeasing the Song Dynasty A year before Li Yu ascended the throne, Southern Tang's nominal overlord Later Zhou had been replaced by the Song dynasty established by former Later Zhou general Zhao Kuangyin, who had earlier participated in several campaigns against Southern Tang. Knowing the limit of Southern Tang's military strength and trying hard to be subservient to the northern court, Li Yu immediately sent a high official Feng Yanlu with a letter — whose language was of extreme humility — to inform Song of his succession. Things got to a rocky start: during his accession to the throne Li Yu built a golden rooster, a symbol of imperial power, the news of which infuriated Zhao Kuangyin. In the end, the Southern Tang ambassador in the Song capital of Bianliang (汴梁; modern Kaifeng, Henan) had to give the explanation that the golden rooster was actually a "weird bird" to satisfy the Song emperor. Such an embarrassing relationship would define Li's entire reign, as tribute payments, both regular and irregular, drained the Southern Tang treasury. Essentially Li was ready to fulfill Emperor Taizu of Song's every demand except go to Bianliang himself. In 963, Li Congshan who accompanied a tributary mission was held hostage in Bianliang and had to write letters on behalf of the Song emperor asking his elder brother also join him at the Song court. Li Yu, naturally, did not heed the request.

Worked examples

Example 1 — a first encounter with Li Yu (Southern Tang)

Start with the simplest possible case. Write down what Li Yu (Southern Tang) 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 Yu (Southern Tang) 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 Yu (Southern Tang) 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 Yu (Southern Tang)

In research
Li Yu (Southern Tang) 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 Yu (Southern Tang) 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 Yu (Southern Tang) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 10th-century Chinese poets, 930s births, 978 deaths, so understanding it makes those chapters shorter.
In everyday life
Look for Li Yu (Southern Tang) 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.
