Whether Shi makes decisions or just carries through Fosun's edicts, personally I think it's a bit of each - they set the financial parameters which seem to be a moving feast and he enacts them.
What is in his control is how he delivers the message. How he does this is appalling, he's an egomaniac, forced out Dalrymple because the fans liked him, fell out with Nuno because he was jealous of him as he didn't get the same level of credit for our success from the fans, hence replacing him with a patsy. Once Thelwell thought his position was untenable, he didn't replace him, just did the job himself with Sellars as another yes man beside him. Getting Vinny into Levy is another example of him exerting his control as that indirectly brings merchandising, retail and catering under his control.
He lies about things which aren't opinion, but a matter of demonstrable fact which then drives divisions within the fanbase.
He's never understood fan mindset, culture or the economic backdrop of the area and never really tried, such is his arrogance. He probably doesn't care about that, if he did there's no way he could have let that pre st price piece go out in the e&s and clearly the pr team don't have the strength or empowerment to guide him.
Basically if Fosun want to start mending fences, which I doubt they do, or even know that they need mending, then fucking Shi off is the only starting point.
