Classification: Jasic Technology worker and labor organizer from Jiangxi; detained since July 2018 in connection with the 2018 Jasic union-organizing case; charged with “gathering a crowd to disrupt social order.” No trial, verdict, sentence, or release has been publicly documented.
Background
Yu Juncong (余浚聪) was born on November 12, 1993, in Shangrao, Jiangxi Province, according to a 2019 filing by Chinese Human Rights Defenders. He joined the Jasic Technology welding-equipment factory in Shenzhen’s Pingshan District in January 2017. An account of his life based on his wife Huang Lanfeng’s recollections, published by the U.S. labor publication Labor Notes, describes him as an avid student of labor law who repeatedly raised grievances over the factory’s scheduling practices, punitive fines, and mandatory company hikes.
Union organizing and firing
In May 2018, Yu took the lead in drafting a joint letter calling on Jasic to cancel its illegal fine system, end forced company hikes, stop the beating and scolding of workers, and allow workers to form a union. According to the Chinese Human Rights Defenders’ prisoners database, he, Liu Penghua, and Zhang Baoxin collected 28 signatures and submitted the letter to the Pingshan District union on May 10, 2018 — the same day Jasic fired Yu. Labor Notes reports that his dismissal notice cited “skipping work,” an excuse his account says was fabricated after he recorded a warehouse manager yelling at him.
Detention
On July 27, 2018, Yu attempted to re-enter the factory with other fired workers; he was arrested along with his wife and younger brother who had come in support, Labor Notes reported. Chinese Human Rights Defenders’ 2019 submission to United Nations Special Procedures records his detention at the Shenzhen Municipal No. 2 Detention Center and states that the exact date of his formal arrest is unknown because no notification was given to his family or lawyer. A December 2018 bulletin by Human Rights in China reported that after a lawyer met with Yu on August 30, the lawyer was pressured to withdraw, and Yu’s requests to meet a new lawyer were not accepted.
The charge reported by Chinese Human Rights Defenders and Human Rights in China is “gathering a crowd to disrupt social order” (聚众扰乱社会秩序). The initial reason given at arrest was “picking quarrels and provoking trouble” (寻衅滋事). An August 24, 2018 Xinhua report on the Jasic incident characterized Yu, Liu Penghua, and Mi Jiuping as having acted under the direction of a workers’ center staff member — a characterization the labor-rights groups dispute in their reporting.
Current status
The Rights Defense Network’s monthly in-custody report for August 2026 lists Yu Juncong in its Guangdong “detained, not yet sentenced” (羁押未判) group. That listing is preserved here as a dated classification; given the age of the underlying case, it is not treated as independent confirmation of his current custody. No trial, verdict, sentence, release, or official disposition has been located in any source consulted. (The roster’s English spelling “Yu Junccong” is a transcription variant of the same person.)
