Person profile: Yu Juncong / 余浚聪
This page collects the published reporting on the case of Yu Juncong (余浚聪), a Jasic Technology worker detained in the 2018 Jasic union-organizing case in Shenzhen, with source attributions and the limits of what is known. All case details are reported as attributed to their sources.
Identity note: The Chinese form 余浚聪 is verified against the Rights Defense Network’s Issue 131 Chinese edition, which places him in the Guangdong “detained, not yet sentenced” group alongside fellow Jasic detainees Liu Penghua, Li Zhan, and Fu Changguo. The roster’s English spelling “Yu Junccong” is a transcription variant of the same person.

- Wikipedia — 佳士事件 (Jasic incident): corroborates May 10, 2018 firing (citing workers’ open letter); notes September 3, 2018 police actions (formal arrest of Liu Penghua; “soft detention” of Mi, Yu, and Li — flagged on-page as needing citation); summarizes the August 24, 2018 Xinhua report naming Yu Juncong among workers said to have been directed by a workers’ center staff member.

Evidentiary limitations
- Sources disagree on the formal-arrest record: the CHRD prisoners database gives September 3, 2018 as the arrest date for Yu with three fellow workers; CHRD’s March 2019 UN filing states the exact formal-arrest date is unknown because no notification reached family or lawyer; Wikipedia describes a September 3 “soft detention” (flagged as needing citation).
- Detention location is reported as Shenzhen Municipal No. 2 Detention Center (CHRD, HRIC, Labor Notes) but as Shenzhen Longgang District Detention Center in the CHRD prisoners database — unresolved.
- The August 24, 2018 Xinhua characterization (workers directed by a workers’ center staff member) is recorded as an attributed official claim, not an established fact; the labor-rights groups’ accounts differ.
- The Labor Notes profile is based on his wife Huang Lanfeng’s recollections as told to the writer — family-attributed, not independently verified.
- No trial, verdict, sentence, release, or official disposition has been located. The August 2026 roster listing may be stale; it is preserved as a dated classification.
