HSKReadyGet the appHSK 5 Fixed Phrase: A的A，B的B
The fixed phrase A的A，B的B describes a plural group in which some members do or experience A while others do or experience B. The first A or B before 的 acts like a nominalized subgroup ('those who A'), and the second repeats the verb or adjective as the predicate ('do A' or 'are A').
毕业以后，同学们走的走，留的留。
Uses contrasting monosyllabic verbs (走 and 留) to summarize how a group of classmates split along different paths.
× 昨天晚上，小王看书的看书，听音乐的听音乐。
Incorrect for the intended single-person scene: the repeated subgroup pattern does not express Xiao Wang alternating activities. Keep Xiao Wang as the subject and use 一会儿看书，一会儿听音乐.
Corrected example: 昨天晚上，小王一会儿看书，一会儿听音乐。

Core Meaning and Grammatical Logic
The supplied HSK 5 outline lists A的A，B的B among its fixed patterns. It describes different members of a group through their actions or states. The group can be explicit or understood; a Chinese noun need not carry 们 to refer to multiple members, as in 这箱水果.
Although the repetition looks idiomatic at first glance, its internal structure follows standard Chinese grammar. In each half of the phrase, the first A combines with 的 to form a headless noun phrase meaning 'those who A' or 'the ones that are A'. The second A then serves as the main predicate for that subset, meaning 'do A' or 'are in state A'. Put together, 'A的A，B的B' literally translates to 'those who A do A, and those who B do B'.

What Can Fill Slots A and B?
A and B should make a coherent description of the group. Common choices are short verbs, adjectives or verb phrases. They need not have exactly the same word-class label: 孩子们睡的睡，困的困 combines an action with a state. The relation in the scene matters more than a mechanical part-of-speech test.
- Monosyllabic verbs: Often pairs of contrasting or alternative actions, such as leaving versus staying (走 / 留), crying versus laughing (哭 / 笑), or buying versus selling (买 / 卖).
- State adjectives: 烂/干 describes the damaged fruit; 忙/闲 can contrast how occupied people are. Such descriptions can be negative or neutral. 丢, meaning “lose,” should not simply be labeled an adjective.
- Short verb-object phrases: Used to paint a lively scene where people in a space are engaged in different pastimes, such as drinking tea versus chatting (喝茶 / 聊天) or taking photos versus shopping (拍照 / 买东西).
这箱水果放了太久，烂的烂，干的干，已经不能吃了。
Uses monosyllabic state adjectives (烂 and 干) to describe different damaged conditions across a batch of items.
休息的时候，大家喝茶的喝茶，聊天的聊天，气氛很轻松。
Uses disyllabic verb-object phrases (喝茶 and 聊天) to depict a lively group scene.
Useful Contrast: A的A，B的B vs. 有的……有的……
Learners often notice that A的A，B的B expresses a meaning very similar to 有的……有的…… (some... others...). While both divide a larger group into smaller subsets, they differ in rhythm, conciseness, and structural flexibility.
- Length: 有的……有的…… readily accommodates fuller descriptions. A的A，B的B is often compact and repeats the core expression, but natural expanded forms also exist. Do not infer a fixed syllable maximum from the short model.
- Rhythm and tone: A的A，B的B sounds brisk, vivid, and summarizing. It often conveys the impression of a bustling scene or a group scattering in different directions all at once.
- Expansion: learn the short form first. Related natural structures can include modifiers, such as 该休息的休息，该工作的工作. Judge the whole expression; do not treat every added modal or negative word as automatically wrong.
公园里的人很多，有的在跑步，有的在跳舞。
Shows the standard 有的……有的…… pattern, which easily accommodates progressive markers like 在 before the verbs.
Structural Limits and Common Learner Mistakes
Because A的A，B的B works by partitioning a collection into subgroups ('those who do A' versus 'those who do B'), the topic or subject must be plural or a collective noun. A single individual cannot be divided into 'the ones who do A' and 'the ones who do B'.
In the intended meaning below, Xiao Wang alone alternates between reading and music. A的A，B的B would suggest different members of a group, so use 一会儿……一会儿…… to keep that single-person meaning. Replacing Xiao Wang with several roommates would change the intended scene rather than correct it.
× 昨天晚上，小王看书的看书，听音乐的听音乐。
Incorrect for the intended single-person scene: the repeated subgroup pattern does not express Xiao Wang alternating activities. Keep Xiao Wang as the subject and use 一会儿看书，一会儿听音乐.
Corrected example: 昨天晚上，小王一会儿看书，一会儿听音乐。
昨天晚上，小王一会儿看书，一会儿听音乐。
一会儿……一会儿…… keeps one person doing activities at different times. This corrects the intended meaning without changing the participants into a plural group.
Frequently asked questions
Can this pattern be extended to three items, like A的A，B的B，C的C?
Yes, in natural Chinese you can occasionally add a third parallel clause when describing a particularly busy scene or a large group dividing into three actions, though the two-part A的A，B的B form is the standard fixed phrase taught in the syllabus.
Can simple nouns be placed directly into the A and B slots?
The slots need a natural predicative reading in this pattern. Verbs and adjectives are the clearest basic choices. Do not put unrelated nouns into the frame merely because they fit the letter A or B; what matters is how the expression predicates an action, state or category of the subgroup.
Do I need to add aspect markers like 了 or 过 inside A的A，B的B?
No aspect marker is required simply because the scene is in the past. The short model often uses bare expressions, with the time supplied by 昨天 or earlier context. Expanded parallel 的 phrases may contain more material, so do not turn that learning model into a universal ban on 了 or 过 in every related construction.
