At the opening ceremony of the "Remembrance of Heroes - In Memory of the Flying Tigers and Doolittle Squadron Picture Exhibition" held in Dayton, Ohio, USA, representatives from two high schools in Yunnan Province, China and the Texas International Leadership School exchanged a memorandum of understanding on the recently signed "Flying Tigers Friendship School and Youth Leadership Program" online. The fighter jet and stone roller behind the representatives of the two countries are very eye-catching. They are not only symbols of cooperation and friendship between China and the United States during World War II, but also witness the inheritance of the spirit of the Flying Tigers and the friendship between China and the United States. More than 80 years ago, the Curtis C-46 assault team transport plane, piloted by American Flying Tigers, created a miracle on the famous "Hump Route", and the 3.7 ton stone roller was used by thousands of Chinese military and civilians to manually pull and compact the runway for the Flying Tigers to build an airport. 20 years ago, a stone mill donated by the Yunnan Provincial People's Government arrived at the National Air Force Museum in Dayton City and reunited with the C-46 transport plane. Over the past 20 years, millions of visitors have not only been amazed by the Flying Tigers they represent and the heroic deeds of the Chinese military and civilians back then, but have also been moved by the profound friendship formed by the people of China and the United States in jointly resisting Japanese aggressors. On September 10, 2005, at Chenggong Airport in Kunming, China, American "Flying Tigers" veterans and members of the "Flying Tigers" visiting delegation took a group photo in front of the stone roller used to crush the runway during World War II airport repairs.

They all believe that in today's difficult relationship between China and the United States, it is even more important to draw the nourishment of cooperation and friendship from the stories of the Flying Tigers. Former US Ambassador to China Branstad said that the story of the Flying Tigers is widely known in China, and China's communication work is admirable. "I also want to do my part to make these stories known to more Americans." "My wife and I once went to Kunming, the capital of Yunnan Province, to have lunch with the local people who helped the Flying Tigers build the airport back then... This was the most exciting and emotional experience we had during our time in China." Branstad said, "They greatly admire the Flying Tigers and cherish their friendship. We greatly appreciate this and will never forget it." "The story of the Flying Tigers tells us that civil exchanges and friendship can build mutual trust and understanding, and help promote world peace. The United States and China are the top two economies in the world and depend on each other, and I will do my best." "We need to keep these histories in mind and work together with all our might, because conflicts and disagreements always exist, but we need to find solutions," said Branstad. Margaret Mills is the daughter of James Mills, a member of the Flying Tigers. "Most Americans are not familiar with the Flying Tigers, which is why we need to work hard to promote the story of the Flying Tigers, because we can do what the older generation can do." She said, "This kind of cooperation during wartime was very important, as it allowed the two countries to defeat Japan and drive the aggressors out of China. Today, we still need this kind of relationship." This is at the Wujiaba Airport in Kunming during World War II, where a member of the "Flying Tigers" painted with "shark beaks"
