On October 29, a netizen posted a video accusing the Hulunbuir Army Border Defense Force border project (Heimeng project), for which the CSCEC Sixth Division is the general contractor, of long-term wage arrears for migrant workers since construction began in 2020. The project has long been completed, but workers have repeatedly failed to receive their pay and are now speaking out online, pleading with the competent authorities to supervise the matter.
