Learn what “该上课的上课” means in Chinese, how to identify the different roles of repeated words, and the grammar behind this compact “those who should do X, do X” sentence pattern.
周一愉快 (zhōu yī yú kuài) — Happy Monday
周一 – zhōu yī – Monday
愉快 – yú kuài – happy (pleasant)
! Adjectives that describe a noun (like a day, time, or event) usually come before the noun (as an adjective)
打起精神 (dǎ qǐ jīng shén) — Cheer up
打起– dǎ qǐ – to rouse up
精神 – jīng shén – spirit (energy)
该上课的上课 (gāi shàng kè de shàng kè) — Those who should go to class, go to class
该 – gāi – should
上 – shàng – to go up
= 上课 – shàng kè – to go to class
!Here, 上课 is part of a small clause that describes who we’re talking about:“those who should go to class”
的 – de – nominalizer: it turns the phrase 该上课的 into a noun‑like expression meaning:
“those who should attend class.”
上课 – shàng kè – go to class
!After 的 this is the main verb of the sentence
In reality, the core meaning of 上课 (“go to / attend class”) is the same both times. The difference here is syntax, not meaning: one is inside a noun‑like phrase (该上课的), one is outside, as the main verb of the sentence. Chinese loves this kind of compact, parallel structure:
- 该走的走
“Those who should leave, leave.” - 该睡的睡
“Those who should sleep, sleep.”
In all of these, the verb (走 / 睡 / 上课) is repeated, but the first is part of the subject‑description, and the second is the action. So no, the meaning of 上课 does not really change; only its grammatical role in the sentence.

班 – bān – shift / work

的 – de – (nominalizer) those who
上班 – shàng bān – go to work
退休的继续休息 (tuì xiū de jì xù xiū xi) — Retired people, keep resting
