Xu joined a cross-border drug gang in late 2024 and took instructions through an overseas chat app.[1][2] He flew three times to a Southeast Asian country — in January, February and April 2025 — carrying packages of cannabis into China, and buried the goods in batches in Changsha, Guangzhou, Shenzhen and Shanghai, earning 30,000 yuan a trip.[1][2]

Police identified him in July 2025 while working on a separate drug-selling case and arrested him in September 2025.[1][2] No cannabis or burial tools were recovered and he had deleted his chat records, but prosecutors traced his bank flows, flight and car-hire records and his online orders for a shovel and waterproof tape, and technical investigators recovered deleted phone data.[2] He finally admitted three smuggling trips totalling more than four kilograms, five cross-province transfers and burials at nearly 100 sites, returned 25,000 yuan of his earnings and gave information on the gang.[1][2]

The Jing’an District Procuratorate indicted him on 18 March 2026, and the Jing’an court sentenced him to four years in prison and a 10,000-yuan fine on 30 March for smuggling and transporting drugs; the judgment has taken effect.[1][2]
