Lu Xun's poems
Explanation:
Most heroes choose the former between righteousness and emotion, and achieve righteousness. So it seems heartless. This is heartless love.
Ruthlessness seems heartless, but it is not a hero.
Seemingly affectionate, but actually playing with feelings, this is affectionate and heartless. Not a hero.
However, being able to take care of your children while achieving righteousness is less sad than being heartless, and more happiness and happiness are immeasurable. This is sentimental, isn't it a gentleman?
