Han Zhiming is definitely not out of the picture. He is very much still the CEO of Zhongi Mingyang and just releasted a Chinese New Year Speech on Feb 11 via WeChat.
I think what is going on with the change in Presidency is a result of Wang getting caught up in that Passport investigation. To my knowledge, he was not charged with anything, but was a "bystander" who was brought into the situation that others were charged for. Whether that is true or not, I don't know, but he was released and was able to return home. I think the brand/image may be a bit bruised now because of it, so they have switched ownership for public views. Think of what happened with Elon Musk manipulating shares via tweets. They removed him from chairman position, yet he still sits as CEO. I think this is the same situation.
What I want to see is another direct link with Han indicating that JBZY is the ticker they are associated with in the US market and that Jinbo is still a player in the company.
I would also like to see what Jinbo's company website looks like. For a corporation as large as they seem (resorts, satellites, cars, etc), they should have a good footprint online, yet I still have not seen it. (I acknowledge I am not a part of the Chinese online community, so I may not be aware if there is a Chinese website set up... if there is, show me please).
Some might say there is no information showing any of the past info has been correct, but there also has not been any info showing it's not. There is just a bit of silence with random changes to the WSOS. I can't even google Lin and link him to Jinbo or JBZY.
Time will tell I guess.
