Jump to last most of private enterprises

I,ve seen around the age of 40 mostly foreign manager has quit, jump to last most of private enterprises, For example, Jun Tang. The success of foreign workers is largely the company is success, not individual success, but Siemens did the United States than the country great, but it does not mean that Siemens China country manager for the United States than the owner of strong, or even far worse. and into the foreign enterprises are often not understood this very early, 90% of his success due to their ability, in fact, foreign companies do not arbitrarily give another performance, general manager of China what a great impact.
