Using the Borrowed Measure Word 包 (bāo) for Packets and Bags
In Chinese, the noun 包 (bāo, bag or packet) is frequently borrowed to function as a nominal measure word (名量词) for items sold, stored, or wrapped in bags, pouches, or packets.
我买了一包茶叶。
Here 包 (bāo) quantifies a loose substance (tea leaves) sold in a sealed pouch or packet.
× 请帮我买一个白糖。
To ask for a packaged unit of white sugar, use 包 or 袋 rather than the generic individual classifier 个.

What Makes 包 (bāo) a Borrowed Measure Word
In the HSK 2 grammar syllabus, 包 (bāo) is categorized under nominal measure words (名量词) specifically as a borrowed nominal measure word (借用名量词). Originally, 包 (bāo) is a regular noun referring to a bag, sack, pouch, or bundle. Because physical containers provide a natural way to group and count things, Mandarin borrows container nouns directly into the measure word slot.
When used as a measure word, 包 (bāo) translates to English expressions like "a pack of," "a packet of," "a bag of," or "a pouch of." It quantifies either mass nouns that cannot be counted individually—such as sugar, salt, or tea leaves—or collections of small countable items packaged together for convenience, such as cookies, tissues, or candies.
Core Sentence Structures
Like other nominal measure words in Chinese, 包 (bāo) sits directly between a number (or demonstrative pronoun) and the noun being quantified. When the numeral is 一 (yī, one), remember that in standard spoken Mandarin its tone changes to the second tone (yí) before a fourth-tone syllable, and to the fourth tone (yì) before a first-tone syllable like 包 (bāo), though dictionaries often print the base first tone.
我买了一包茶叶。
Here 包 (bāo) quantifies a loose substance (tea leaves) sold in a sealed pouch or packet.
桌子上有两包饼干。
Note the use of 两 (liǎng) rather than 二 (èr) for the number two before the measure word 包 (bāo).
When pointing out a specific packet using 这 (zhè, this) or 那 (nà, that), the numeral 一 (yī, one) is frequently omitted in everyday conversation without changing the grammatical role of 包 (bāo).
请把那包纸巾给我。
The numeral 一 (yī) is naturally omitted between the demonstrative 那 (nà) and the measure word 包 (bāo).
Natural Contexts and Common Collocations
You will encounter 包 (bāo) most often when shopping at supermarkets, ordering groceries, or organizing household supplies. It typically pairs with items sealed in paper, plastic, or foil wrapping, as well as things bundled in cloth or paper.
- Small packaged snacks and dry foods: 饼干 (bǐnggān, cookies/biscuits), 糖 (táng, candy/sugar), 薯片 (shǔpiàn, potato chips), 巧克力 (qiǎokèlì, chocolates).
- Packaged kitchen staples: 茶叶 (cháyè, tea leaves), 白糖 (báitáng, white sugar), 盐 (yán, salt), 咖啡 (kāfēi, coffee powder/beans), and 牛奶 (niúnǎi, milk in soft pouches). 包 counts the packaged unit, not the liquid or powder by itself.
- Daily household and personal items kept in soft packs: 纸巾 (zhǐjīn, paper tissues), 湿巾 (shījīn, wet wipes), 药 (yào, medicine powders or packets of pills).
Useful Contrasts: Noun vs. Measure Word, and Individual vs. Packaged
Learners should first distinguish whether 包 (bāo) is acting as the main noun of the phrase or as the measure word. When someone talks about buying or carrying a handbag, backpack, or wallet, 包 (bāo) is the noun at the end of the phrase, and it takes its own measure word—usually 个 (gè) or 只 (zhī). When 包 (bāo) is the measure word, another noun must follow it (unless that noun is omitted because both speakers already know what substance is inside).
这个包很漂亮。
Here 包 (bāo) is a standalone noun meaning 'bag' or 'handbag', quantified by the measure word 个 (gè).
Second, using 包 (bāo) contrasts with individual measure words like 个 (gè), 块 (kuài, piece/chunk), or 张 (zhāng, flat sheet). Choosing between them changes the real-world quantity you are describing. For example, counting candy with 块 (kuài) refers to a single piece, whereas counting with 包 (bāo) refers to an entire bag of candies.
孩子吃了一块糖。
Using the individual measure word 块 (kuài) specifies one single piece of candy.
妈妈买了一包糖。
Using the borrowed container measure word 包 (bāo) specifies a whole packet of candies.
Common Learner Mistake and Practical Limits
A frequent mistake among beginners is overusing the general measure word 个 (gè) with mass or granular nouns when asking for a packaged unit at a store. Fine granules like white sugar (白糖, báitáng) or salt (盐, yán) do not come in single solid units that can be counted with 个 (gè). If you ask someone to buy a bag of sugar from the supermarket, using 个 (gè) is ungrammatical; you must use a container measure word such as 包 (bāo) or 袋 (dài, bag/sack).
× 请帮我买一个白糖。
To ask for a packaged unit of white sugar, use 包 or 袋 rather than the generic individual classifier 个.
Corrected example: 请帮我买一包白糖。
请帮我买一包白糖。
包 counts the packet containing the sugar.
Keep in mind that 包 (bāo) also has physical limits. It applies to soft packets, wrapped bundles, or flexible pouches. If an item is packaged in a rigid cardboard box or plastic case, Chinese speakers typically choose 盒 (hé, small box/case) or 箱 (xiāng, large carton/crate) instead. Similarly, while 包 (bāo) and 袋 (dài) overlap for many supermarket pouches, 袋 (dài) emphasizes a sack or openable bag (like a plastic shopping bag or a heavy sack of flour), whereas 包 (bāo) emphasizes a sealed packet or wrapped parcel.
Frequently asked questions
Can I use 包 (bāo) and 袋 (dài) interchangeably?
They often overlap for small supermarket items like potato chips, sugar, or milk pouches. However, 包 (bāo) focuses on a wrapped packet or sealed parcel (such as a pack of tissues or a foil packet of tea), while 袋 (dài) focuses on a bag or sack container (such as a plastic carrier bag or a large sack of rice).
Where do I put adjectives like 'big' or 'small' when using 包 (bāo)?
To describe the size of the packet itself, you can place adjectives like 大 (dà, big) or 小 (xiǎo, small) directly before the measure word, forming phrases like 一大包饼干 (yí dà bāo bǐnggān, one big pack of cookies).
How is 一 (yī) pronounced in 一包 (yì bāo)?
Because 包 (bāo) is pronounced in the first tone, the numeral 一 (yī) undergoes standard tone sandhi in natural speech and is pronounced in the fourth tone: yì bāo.
