Tong, Jian, and Ti: Pu'er's Units of Measure
Hear "How much is a tong of this?" or "It's cheaper by the case" in a tea shop, and first-time pu'er buyers often pause: how much is a tong, and how much is a case? These units come from the tradition of long-distance shipping and export of Yunnan tea, and they're still the common language of the pu'er trade today.
A Tong: Seven Cakes Stacked Together
Traditional Qizi cakes are stacked seven high, wrapped in zhuruo (bamboo sheath, the husk from bamboo shoots), and tied tight with bamboo strips or string. That stack is one "tong."
- 357 g per cake × 7 cakes = 2,499 g, about 2.5 kg per tong
- With 400 g cakes, a tong is about 2.8 kg
- With 500 g large cakes, a tong is about 3.5 kg
The tradition of seven cakes per tong goes back to the Qing dynasty. Qing statutes record that under Yongzheng, pu'er round tea was set at seven rounds per tong, each tong weighing 49 liang, with taxes levied by the tong. Today's 357 grams is a modern export spec: after the market system changed to 1 jin = 500 grams in 1959, export cases of 30 kilograms held 84 cakes, averaging about 357 grams each. For the origin of Qizi cakes, read Qizi Cakes and 357 Grams.
Smaller cakes aren't necessarily seven to a tong. Common examples listed in English-language pu'er sources include 250-gram small cakes at five per tong and 100-gram mini cakes at ten per tong. Practices vary by maker, so go by what the packaging says. The various cake formats are in Cake Sizes.
A Jian (Case): 12 Tong, About 30 Kilograms
Twelve tong are packed into one "jian," or case. Calculated with 357-gram cakes:
- 12 tong × 7 cakes = 84 cakes
- 84 cakes × 357 g ≈ 30 kg
In the early days whole cases were shipped in bamboo baskets; today cartons are common too. The case is the unit factories ship in and wholesalers buy in; ordinary consumers rarely buy a whole case. Note also that not every maker fixes a case at 12 tong; some factories or formats vary it, so checking the stated number of cakes and total weight before ordering is the most reliable approach.
A Ti: A Common Colloquial Term
"Ti" (提, literally "a carry") is a colloquial unit, used more loosely than tong or jian. The most common usage in the tea world is one ti = one tong = seven cakes, the stack you "carry" by hand. Some sellers also call a carry bag or a gift set a ti, with the number of cakes depending on the product. When you hear "one ti," just ask how many cakes and how much each weighs, and there'll be no misunderstanding.
Conversion Summary
| Unit | Contents | With 357 g cakes |
|---|---|---|
| Cake | 1 tea cake | 357 g |
| Tong | 7 cakes | About 2.5 kg |
| Ti | Commonly 1 tong, depending on the seller | About 2.5 kg |
| Jian (case) | 12 tong, 84 cakes | About 30 kg |
Why Buying a Whole Tong or Case Is Often Cheaper
Many tea shops offer a lower unit price for whole tong and cases than for single cakes. The reasons are practical:
- Packaging and labor: Shipping a whole tong means no unwrapping and no individual repacking of each cake.
- Selling costs: Selling more at once spreads order handling and shipping costs more thinly.
- Wholesale habits: Tea has always circulated among wholesalers by the case and the tong; single cakes are split-off retail.
A lower unit price doesn't mean it suits everyone. With a whole tong or case, consider whether you have suitable storage space at home, whether you'll drink it all, and whether you really like this tea. Buying one cake or a small sample first and topping up if you like it is the more relaxed approach. See Cake, Tong, or Case: How Much to Buy and How Much to Store and Buy a Small Amount First.
Tips for Storing a Whole Tong
- Bamboo sheath breathes, so there's no need to open a tong for storage; just leave it as it is.
- Keep the tong ticket or dapiao from inside the tong, and set it aside when you open it. See Neipiao and Dapiao.
- The general rule for storage is cool, ventilated, dark, and free of odors; details are in How to Store Pu'er at Home.
