After the end of World War II, British Prime Minister Winston Churchill was a great hero and a hero who led the war to victory. However, when China was elected Prime Minister, he lost the election, not because he was old. He retired from the political arena with regret. Later, he quoted the ancient Greek writer Plutarch as saying: "It is a symbol of a great nation to be ungrateful to your great man."

The reason why a great nation can be handed down is that they have been moving forward instead of looking back, leaving their sufferings behind and focusing on the road ahead. There is no need to continue to bear the burden of the past, and surviving is the best result. However, when the whole nation encounters disaster, great people will unite to bear the disaster. After bad luck, move on.
