Fermat's conjecture, a seemingly simple question, has attracted the attention of many mathematicians in history for 350 years since it was put forward, but it also makes these once most outstanding brains feel distressed and depressed. Fermat's conjecture is just a Mount Everest that stands in the minds of mathematicians. Fermat, Leibniz, Euler, Gauss, Legendre, Dirichlet, Lame, LeBerg, Cuomo, Godel, Yutaka Taniyama, Village of Goro, faltings and other most luxurious star lineups have appeared one after another. Unfortunately, none of them can find a way to climb the mountain. Later generations can only continue to climb in the mountaineering camp built by their predecessors. No one can know whether overcoming Fermat's conjecture is a dream that people will be able to break through all obstacles or a mirage condensed in the hearts of countless people.

It means that the doubt is solved, which means that he is strong.
