Great national joke

There are four people going by plane, namely Americans, Germans, China and Japanese. When flying in the air, the captain said that something had happened to the plane. Now the plane is too heavy to jump. At this time, the Americans stood up, shouted "Long live the United States of America" in front of the plane and jumped. After a while, the captain said it was too heavy and wanted to jump again. The German stood up, shouted "Long live Germany" and jumped. After a while, the captain still said it was too heavy and he had to jump himself. At this time, the Japanese came forward. When the Japanese saw it, they quickly shook hands with porcelain and said thank you. Only when the Chinese shouted "Long live People's Republic of China (PRC)" did they kick the Japanese down.
