"ZJMY has been a shareholder of Long Star as far back as I can remember...in one way or another." **Yes agree ZJMY has been listed as a shareholder far back. Very strange how it was never a corporate shareholder rather natural persons.
"Han Zhiming is the current president of ZJMY." **I would assume so with his 49% share ownership.
"JB&ZJMY Holding co also know as JBZY owns the remainder of share of Long Star" **Time will tell on that one...
"they can't disclose that ownership to the public just yet" **That is not how it works in China
