Hello sir, good day to you! I have a concern that you may be able to put to rest. I was looking into the current accounting firm for the company, namely, De Leon & Company. When I look at this companys clients I see that almost all of them are really small companies including ones being traded on the OTCMRKTS. Why, if Jinbo is such a big company with billions in assets, did it not employ a reputable company like Price Waterhouse Coopers, similar to say TESLA? Or any of the bigger firms? How is a small scope auditor like de Leon, based in Florida, going to audit a company and its assets based out of China?
My sister is an auditor or PwC and tells me that when they are to audit a company based somewhere else, they have to go there to audit them. That's the only way to audit a company and its assets. Are we to assume that De LEON and company has the resources and wherewithal to go to China to do Jinbo's audit, which is supposed to be such a HUGE company?

I'm becoming sceptical and don't know the legitimacy of this company.
