Specialized Noun Classifiers 打, 袋, 根, 卷, 棵, and 批 in Chinese
打 / 袋 / 根 / 卷 / 棵 / 批
These classifiers package nouns by conventional unit or shape: 打 counts dozens, 袋 bags, 根 long narrow objects, 卷 rolls, 棵 rooted plants, and 批 batches or groups handled together. They occupy the classifier slot between a number or demonstrative and the noun. Selection depends on the noun and intended unit, not English translation alone.

Read the structure
These classifiers package nouns by conventional unit or shape: 打 counts dozens, 袋 bags, 根 long narrow objects, 卷 rolls, 棵 rooted plants, and 批 batches or groups handled together. They occupy the classifier slot between a number or demonstrative and the noun. Selection depends on the noun and intended unit, not English translation alone. Keep the model Number or demonstrative + specialized classifier + noun visible while you compare each sentence.
我们买了两打铅笔。
We bought two dozen pencils.
Choose the right context
Use 打 for a dozen and 袋 for contents counted by bags. Use 根 for long narrow objects, 卷 for rolls, and 棵 for rooted plants. Use 批 for goods, people, or work treated as one batch.
院子里有三棵树。
There are three trees in the yard.
Respect the boundary
Do not replace every specialized classifier with 个 in careful quantity phrases. Do not put the classifier after the noun. Do not choose only by physical shape when the noun has a conventional classifier-unit pairing.
我们买了铅笔两打。
(We bought two dozen pencils.)
Repair the pattern
The classifier follows its noun: A counted noun phrase places number and classifier before the noun: 两打铅笔. A plant takes the long-object classifier instead of the plant classifier: Rooted plants conventionally take 棵. 根 may count long narrow objects or roots, but not a whole tree here.
我们买了两打铅笔。
Use the repaired structure without changing the intended meaning.

08 / QUESTIONS
Specialized Noun Classifiers 打, 袋, 根, 卷, 棵, and 批 Questions
Can 个 replace these classifiers?
个 may occur colloquially with some nouns, but it cannot preserve meanings such as a dozen, a bagful, a roll, or a batch. Use the specialized classifier when that unit matters.
What is the difference between 根 and 棵?
根 counts long narrow objects such as ropes or sticks and can count roots themselves. 棵 counts whole rooted plants such as trees and cabbages.
