That figure is grossly understated IMO. 100-499 employees is a copy/paste number that has been tossed around for months, and I would bet the company could now have over 1,000 working for it.
There are probably subcontract/co-op agreements with Long Star/Chery and others who are also working on Jinbo/ZJMY projects not included in employment figures. Not to mention independent agents affiliated with other Jinbo entities.
