Old Ford, the founder of Ford Motor Company, invented a black Model T with simple structure and low cost through his own research. His Ford Motor Company has achieved great success, and he has deep feelings for the products he created. Later, the market changed a lot and people's consumption level improved. They are no longer satisfied with such products, but pursue high-grade and personalized products. But he ignored this change and stubbornly only produced his own black Model T car. His son grasps the changing trend of the market and organizes manpower and material resources to develop new products to adapt to the changing market. However, because of his special affection for the black Model T, Old Ford could not see the changes in the market and refused to adapt. He arbitrarily denied his son's efforts and publicly vilified his son's new product. His enterprise also paid a heavy price for this decision, and lost to General Motors forever, which is far from the leading position in the automobile industry.

2. In order to make a new breakthrough in the 2002 Winter Olympics in Salt Lake City, coach Yao Bin changed Shen Xue/Zhao Hongbo's free skating program to Turandot in the season of 0102, and invited American director Lian Miller to arrange it. This is a program with both Chinese and Western characteristics, and Yao Bin has integrated the difficult movements of "tossing and turning" that he didn't finish before. Unfortunately, at the Winter Olympics in Salt Lake City, Shen Xue/Zhao Hongbo made a toss-and-turn mistake because of the difficulty of the selected movements and short training time, and finally only won a bronze medal.
