I hope she has business sense , no favoritism, no racism, and respects for all, and especially for those who work hard.

I doubt anyone external would want to take the risk to join YGE at this point so it would have to be be someone quite senior from internally. Having been the CFO seems to mean that there was quite a bit of established trust for her from within the company and main shareholders. Especially during these times when there are rumors of financial woes for YGE, to have the CFO step in to take the CEO position is a smart political move. Really interested to see how she is going to "rebrand" the company. Stepping in to be the new face and driver of YGE is a high risk high reward move on her part.
