Although he was imprisoned after the "Xi incident", he firmly believed that what he did was to resist Japan and save the country. He is unselfish, aboveboard, can learn from heaven, and history will make a fair judgment. Therefore, he suppressed his anger and troubles, smiled at life and enjoyed it.
Second, humor. Zhang Xueliang is famous for his humor. He once said more than once, "If I am shot tomorrow, I can still sleep soundly tonight." Tuanjiebao once reported that 93-year-old Zhang Xueliang told jokes, sang Peking Opera, guessed puzzles and wrote poems at a friend's party, which was really interesting. It can be seen that it is this humorous, optimistic and open-minded character that gives him great vitality.

It is these broad interests that make him enjoy it, be praised or criticized by others, and make him full of energy and stay young forever.
