The truth is, Wang Ye chose to stay because of his understanding of Big Head Kong's experiences!
This man was well-known in the Chinese community in Moscow.
In his previous life, Wang Ye hadn't kept track of when exactly things fell apart for Khodorkovsky or what the final outcome was, even after he returned to China.
But as far as he knew, Big Head Kong always seemed to have had a good life.
He had remained unscathed until Sun Market was eventually closed for good. Afterwards, he reportedly immigrated to Canada, and his whereabouts gradually faded from public knowledge.
So, Wang Ye figured that if he stuck around with Khodorkovsky, merely participating in the operation of Sun Market, he probably wouldn't get tangled up in the affairs of the oil company...
Looking at it this way, the risk seemed quite manageable!
Moreover, how could anyone expect to rake in big bucks and rise to prominence without taking on a bit of risk?
As the saying goes, fortune favours the brave!
