Chinese scientist Wang Juzhen has a motto when it comes to experimental failures: "If you keep doing it, there is still a 50% chance of success. If you don't do it, there is 100% failure."

Famous Chinese mathematician When talking about learning and exploration, Hua Luogeng pointed out: "We must dare to make subtractions in learning, which means subtracting the parts that have been solved by predecessors to see what problems are still unresolved and need us to explore and solve them."
