Zhang Jike decided not to renew his contract with Butterfly due to "commercial constraints." Instead, he has signed on as a global ambassador for Donic. He had previously been with Butterfly for 15 years before making the switch.
Here's the link of the official announcement from Butterfly of Zhang Jike's Termination of Contract just 3 hours ago.
What's your thought on this?
Anyone had an idea of what the "commercial constraints" is about?
It looks like from the article, the termination was an initiative from Butterfly but from my own research from several media outlet, it is a mutual decision.
Whatever the "commercial constraints" are, Butterfly won't fight for it because Zhang Jike is already retired. (Kidding 
)
adriano,
Anyhow, what will Zhang Jike's job be as an global ambassador for Donic?
Global ambassador is a fancy word for endorser. They promote and act as a face of the brand.
