The Han emperors and governments posed as having a temporal dispensation that had received the blessing of heaven together with its instructions to spread the benefits of a cultured life as widely as possible. By a cultured life the Chinese had in mind a clear distinction between their own settled agriculture and the delights of the cities, as opposed to the rough and hardy life spent in the saddle by the nomads of Central Asia. The growth of Han government both depended on and encouraged the development of literary accomplishment, scholastic competence, religious activity, scientific discovery, and technological achievement.

Han administration required detailed recordkeeping, which generated a proliferation of documents. Official returns were sometimes kept in duplicate, and each agency kept running files to record its business. Following a reform of the script that had evolved before the Han period, a new style of writing was developed that was suited to compiling official documents. These were written mostly on bulky and fragile wooden strips; silk was also used as a writing medium. A major development in world history occurred in China in 105 ce when officials reported to the throne the manufacture of a new substance. Although archaeological evidence indicates the existence of paper for more than a century before this incident, the earlier materials were not completely superseded until some three or four centuries later. In the meantime, the written vocabulary of the Chinese had increased in response to the demands of a growing civilization. The first Chinese dictionary, completed in 121 ce, included more than 9,000 separate ideograms (characters), with explanations of their meanings and the variant forms used in writing.

In an attempt to break with earlier tradition, the Qin government had taken certain steps to proscribe literature and learning. Han governments stressed their desire to promote these causes as part of their mission. In particular, they displayed a veneration for works with which Confucius had been associated, either as a collector of texts or as an editor. Beginning during the reign of Wendi, orders were given to search for books lost during the previous dynasty. Knowledge of texts such as the Shijing (“Classic of Poetry”), the Shujing (“Classic of History”), the Yijing (“Classic of Changes”), and the Chunqiu (“Spring and Autumn”) annals became a necessary accomplishment for officials and candidates for the civil service. To support an argument laid before the throne, statesmen would find a relevant quotation from these works; already in the 1st century bce the tradition was being formed whereby the civil service of imperial China was nurtured on a Classical education. On two occasions (51 bce and 79 ce) the government ordered official discussions about interpreting texts and the validity of differing versions; in 175 ce work was completed on a project that inscribed an approved version on stone tablets, so as to allay scholastic doubts in the future. In the meantime—and still before the invention of paper—a collection of literary texts had been made for the imperial library. The catalog of this collection, which dates from the early 1st century ce, was prepared after comparing different copies and eliminating duplicates. The list of titles has been preserved and constitutes China’s first bibliographical list. The works are classified according to subject, but many have been lost. The importance of these measures lies both in their intrinsic achievement and in the example they set for subsequent dynasties.

The prose style of Han writers was later taken as a model of simplicity, and, as a reaction to the literary embellishments and artificialities introduced in the 5th and 6th centuries, deliberate attempts were made to revert to its natural elegance. Examples of this direct prose may be seen in the imperial edicts, the memorials ascribed to statesmen, and, above all, the text of the standard histories themselves, in which such documents of state were incorporated. Compiling the standard histories was a private undertaking in Han times, but it already received imperial patronage and assistance. History was written partly to justify the authority and conduct of the contemporary regime and partly as a matter of pride in Chinese achievement. Further examples of prose writing are the descriptions of protocol for the court. One of the earliest acts of the Han government (c. 200 bce) had been to order the formulation of such modes of behavior as a means of enhancing the dignity of the throne, and one of the latest compilations (c. 175 ce) that still survives is a list of such prescriptions, drawn up at a time when the dynasty was manifestly losing its majesty and natural authority. Some of the emperors were themselves composers of versified prose; their efforts have also been preserved in the standard histories.

The emperor was charged with the solemn duty of securing the blessings of spiritual powers for humankind. One of the nine ministries of state existed to assist in this work of mediation, but from the time of Wudi onward the emperor himself began to play a more active part in worship and sacrifice. The cults were initially addressed to the Five Elements (fire, water, earth, wood, and metal), to the Supreme Unity, and to the Lord of the Soil. In 31 bce these cults were replaced by sacrifices dedicated to heaven and earth. The sites of worship were transferred to the southern and northern outskirts of Chang’an, and a new series of altars and shrines was inaugurated. The Han emperor occasionally paid his respects to supreme powers and reported on the state of the dynasty at the summit of Mount Tai. Wudi’s desire for immortality and for quickening his deceased favorites led him to patronize a number of intermediaries who claimed to possess the secret of making contact with the world of the immortals. From such beliefs and from a fear of the malevolent influences that the unappeased souls of the dead could wreak on humanity, a few philosophers such as Wang Chong (27–c. 100 ce) reacted by propounding an ordered and rational explanation of the universe. But their skepticism received little support. Sometime during the 1st century ce, Buddhism reached China, propagated in all probability by travelers who had taken the Silk Road from northern India. Shortly thereafter Buddhist foundations were established in China, as well as the first official patronage of the faith. From the 2nd century ce there arose a variety of beliefs, practices, and disciplines from which alchemy and scientific experiment were to spring and which were to give rise to Daoism.

Most of the cultural attainments of the Han period derived from imperial encouragement and the needs of officials. A textbook of mathematical problems was probably compiled to assist officials in work such as land assessment; fragments of a medical casebook were concerned with the care of troops and horses serving on the northwestern frontier. Water clocks and sundials were used to enable officials to complete their work on schedule. The palace demanded the services of artists and craftsmen to decorate imperial buildings with paintings and sculptures and to design and execute jades, gold and silver wares, and lacquer bowls for use at the imperial table. Intricate patterns in multicolored silks were woven on looms in the imperial workshops. On a more mundane level, technology served the cause of practical government. The state’s ironwork factories produced precision-made instruments and weapons of war, and the state’s agencies for the salt industry supervised the recovery of brine from deep shafts cut in the rocks of western China. Water engineers planned the construction of dikes to divert the flow of excess waters and the excavation of canals to serve the needs of transport or irrigation, and in many parts of the countryside there could be seen a sight that remained typical of the Chinese landscape up to the 20th century—a team of two or three laborers sitting astride a beam and pedaling the lugs of the “dragon’s backbone” that raised water from the sluggish channels below to the upper levels of the cultivated land.
