In the past, it took several weeks to register an enterprise that needed 30-40 signatures, but now it can be completed in one day. The time and space boundary of enterprise registration is no longer the limiting factor of enterprises. "Jin Xin Office" promotes enterprise registration to be smarter, more convenient and more worry-free.
