1) this is a Chinese RTO. If you think that isn't a red flag, good luck to you. Most stocks that get halted for irregularites are Chinese RTO's. There is a good reason why. No due diligence to go public.
2) the company won't even show where their products are sold. This is not nuclear security, it is fertilizer. Real company's don't hide where their product is sold, they advertise it. Frauds hide it because they don't want it validated. Of course, they all claim "competitive reasons".
These are two simple red flags that should stop people in their tracks from investing in YONG. But keep rationalizing the simple reasons away and the complex stuff won't matter either. I have no position, because can't borrow shares. Nevertheless, this is a fruad to some large degree.
