Among them, Chris Cox is a senior Facebook executive, considered Zuckerberg's right and left hand, in the outside world, he is second only to Zuckerberg and Sandberg's Facebook No. 3 figure, the nail on the board will become Zuckerberg's successor.
Since 2005, Cox has worked for Facebook for 13 years. He is one of the company's first 15 engineers. He has contributed a lot to Facebook products.

But now, Zuckerberg is calming down, trying to break through the obstacles and talk directly to the heads of product departments. WhatsApp will be headed by Will CathCart, currently in charge of Facebook, and Facebook will be headed by Fidji Simo, who runs the video business, he said in the statement. Crucially, Cox's position is vacant, and the person in charge of all applications reports directly to Zuckerberg.
