What cold jokes did Obama tell at the 20 15 White House press dinner?

A few words that American ships are going to cross the sea and are known as "positive energy people": 1, the United States is going to decline and be confused; 2, anyway, there is nothing to lose, love to rush, and let the United States waste costs; 3, let you play now, when I am strong, I won't kill you American ghost; 4, you can rush, don't push me hard, don't act rashly, it doesn't mean never moving, pushing hard, a fatal move; 5. If you can't bear it, make a great plan. I'm making great plans. Final conclusion: win in China, lose in the United States!
