The phrase "please yourself before crossing the mountain" can be understood as that in the process of pursuing goals, people should first make themselves feel satisfied and happy, rather than just paying attention to the result of victory. Only when you feel satisfied and happy can you really enjoy the joy of victory.
Therefore, the sentence "When you win, please please be tolerant of yourself first" can be interpreted as: in the process of pursuing victory, people should take their own interests and happiness as the primary goal, and don't sacrifice their moral principles, values or personal interests in pursuit of victory. At the same time, people should make themselves feel satisfied and happy in the process of pursuing their goals in order to truly enjoy the joy of victory.
