轮询 (lún xún)

--feedback--

This word combines the syllables lún and xún.

--explanation--

The first syllable combines the initial l with the final uen (written as un), and uses the second tone, which rises from mid to high. The second syllable combines the initial x with the final ün (written as xun in Pinyin), and also uses the second tone.

轮询 (lún xún) refers to a method where a system periodically checks for new data or status changes instead of relying on event-driven notifications.
