Zhang Xueliang's evaluation of Jason's talent does not have a general concept. If Zhang has no general idea, how did he change from a poor veterinarian to a king of Northeast China? Just like father and son, right?
Zhang really can say that he doesn't have much strategic vision, but he is good at being a man, doing things and employing people. In fact, many rulers throughout the ages have no general concept. Did Liu Bang? Does Liu Bei have it? It is enough for a man to have it and follow himself faithfully.
As for Zhang Xueliang, he doesn't even have a big talent. Although I can't say that I am like a tiger or a son, I am really far behind my father. Throw him into the green forest in the late Qing dynasty, and it is estimated that there are no bones left.
