Today, the self-published media platform 'Dachang Ribao' released an article revealing that Building 4 within the Xixi C District of Alibaba's global headquarters is rumored to be the site of a "top-secret" project. Sources from within the company indicate that the building has not yet undergone its official opening ceremony. Despite a notice posted downstairs stating, "This building is temporarily closed; please use an alternative route," a dedicated staff member is observed delivering meals every noon, and only one entrance remains accessible. Furthermore, security personnel are stationed at the entrance to verify employee badges, turning away some individuals attempting to enter under the pretext of a "confidential project." While some netizens speculate that the project might be linked to chip technology or AutoNavi (a navigation service provider), AutoNavi has not issued any response to these speculations.
