Note: This article was written in May 2026, based on publicly reported events of the collapse of Wanwuji. The case is still under judicial proceedings, and some information needs further verification.

By the end of February 2026, a supplier rushed to the headquarters building of Wanwuji in Putuo District, Shanghai, to seek an explanation in person.
Upon arrival, they found a notice posted on the glass curtain wall of the building—"Lease Expired."
The access control system was shut down. The 400 customer service hotline only emitted busy signals. The official website's online customer service displayed "Service Suspended."
The once brightly lit office area left not even a single sheet of paper.
This was not the quiet departure of a small workshop.
This was the collapse of an industrial e-commerce unicorn valued at 10.36 billion yuan, with the halos of Sequoia China and Hillhouse Capital.
It was also once listed among the "Top 50 Key Listed Companies in Guangzhou."
Even more outrageous, this collapse was not caused by a sudden earthquake but was a premeditated, step-by-step systemic withdrawal.
Over 1,273 suppliers were owed 218 million yuan in payments, with some companies forced to sell factories or mortgage properties.
Meanwhile, the company's founder, Zhou Yanhua—a PhD in Mechanical Engineering from Tsinghua University, self-proclaimed as a "industry benchmark" with 22 years of experience in industrial product distribution—has already gone offline.
Today, we will analyze this incident.
The Birth of a Billion-Yuan Unicorn
To understand how outrageous this is, first look at how impressive Zhou Yanhua’s background is.
PhD in Mechanical Engineering from Tsinghua University, self-proclaimed as having deep expertise in industrial product distribution for 22 years.
Wanwuji is not a grassroots startup. It evolved from global industrial product distribution.
