Reconstruction
In 59 BCE, a text traditionally attributed to the Han writer Wang Bao described the duties imposed on an enslaved household worker. Commonly known as the “Contract with a Servant,” its long, partly comic list includes instructions usually interpreted as preparing tea and buying tea at Wuyang, a market center in present-day Sichuan. These lines are among the earliest credible written indications that tea was both a deliberately prepared drink and a traded commodity. The work survives through later textual transmission rather than as its original document, however, so its wording and interpretation require care.
The relevant early character, often read as tu, could denote tea but also other bitter plants. Context strengthens the tea reading: the material is purchased at a named market and separately prepared within a household. Even so, the text supplies no complete recipe. “Preparing” or “boiling” tea probably involved heating leaves in water, but it does not establish whether the leaves were fresh, dried, compressed, powdered, strained, seasoned, or consumed with other ingredients. Detailed practices documented centuries later—such as Tang-period tea cakes, grinding, and boiling with salt—cannot simply be projected back onto the Western Han.
Archaeobotanical evidence gives the written reference a broader setting. Tea remains identified from an imperial Han burial indicate that leaves or buds circulated among elites by roughly the second century BCE. Such finds demonstrate the presence and selection of tea material, not its use as a beverage: burial deposits might represent drink ingredients, medicine, valuables, or provisions for the dead. Taken together, however, plant remains and the household text make regional tea consumption increasingly plausible.
Southwestern China was crucial to this early history. Tea plants were native to parts of southern and southwestern East Asia, and Sichuan had environments suitable for their management and cultivation. The journey to Wuyang implied by the contract also shows that tea preparation depended on more than leaves. Markets, roads, containers, fuel, water, household utensils, and labor connected producers and drinkers. The labor relationship was unequal: the document presents tea service as one obligation among many extracted from an enslaved person.
This Han evidence does not mark a single invention of tea. Rather, it captures a stage when a regional plant product had become recognizable enough to purchase and assign as a household preparation task. Over subsequent centuries, cultivation expanded, processing became more specialized, and tea spread through Buddhist institutions, cities, taxation systems, and long-distance trade. Modern loose-leaf and bagged infusions differ substantially from any securely reconstructable Han drink, but the familiar sequence of acquiring leaves, heating water, and serving a stimulating beverage has an early and defensible precedent here.

Historical context
The Western Han empire governed much of China under Emperor Xuan. Its population was already in the tens of millions; the surviving census of 2 CE, several decades later, recorded nearly 60 million people. State roads, river transport, large urban markets, iron tools, and an extensive tax administration moved grain and regional luxuries over long distances. Sichuan’s fertile basin and southern uplands supported intensive farming and exchange, while connections through Central Asia were developing into the routes later called the Silk Roads. Tea was still primarily a southern or southwestern product rather than a universal Chinese daily drink.
Evidence
Written sources
ModerateThe text conventionally dated to 59 BCE lists actions interpreted as preparing tea and purchasing it at Wuyang. It is known through later transmission, and the early plant term is not entirely unambiguous.
Archaeobotanical
StrongTea leaves or buds have been identified in Western Han elite burial contexts, directly supporting the presence and circulation of selected tea material by this broad period.
Food identification
ProbableThe commercial and preparation context supports identification of the written plant term as tea, although the character historically had a wider semantic range that included other bitter plants.
Dating
ModerateThe traditional date of 59 BCE is widely associated with the contract, but the work does not survive as a contemporary excavated manuscript.
Preparation method
LimitedThe text supports deliberate household preparation, commonly translated as boiling or brewing, but provides no secure information about leaf processing, proportions, utensils, filtering, additives, or service.
Geographic attribution
ModerateWuyang is generally associated with the Sichuan region, making southwestern China the relevant commercial setting; the text does not support Hangzhou as the location of the episode.
Historical interpretation
ModerateThe evidence supports tea as a marketed and prepared regional commodity, but not a claim that tea drinking began in 59 BCE or was already common throughout the Han empire.
Recipe evidence
LimitedNo recipe survives in the cited passage. Any reconstruction as a plain strained infusion is a nutritional and visual analogue, not a directly documented Han formula.
Limitations
- majorcoordinates
The supplied coordinates indicate Hangzhou in eastern China, but the 59 BCE tea-purchase reference names Wuyang, generally located in present-day Sichuan. The coordinates materially misplace the documented setting.
- minortitle
The passage is credible early evidence for tea preparation, but it does not preserve a recipe or prove that the resulting beverage resembled modern infused tea.
