It can be seen from different levels of description that there is no crying, why not? Not because I didn't cry, but because everyone has different tolerance for pain. Different pain thresholds (the lowest value of stress tissue response caused by pain stimuli) will lead to different pain feelings for the same stimulus, and whether or not to cry is not because of the simple judgment of gender and age, but the external manifestation of this stimulus.
If you don't cry, you are not strong, and if you don't cry, you are strong. It only represents the external performance of the individual to the stimulus.
After all this verbiage, there is actually only one sentence. When you suffer to a certain extent, crying is not a big deal, but also a normal performance.
