There is too much uncertainty in this world, and I am not willing to let my children face that future by giving birth to children who will face difficult years ahead.
I am a pessimist, I don't think the future of mankind is an optimistic world.
I think the earth will be short of water and short of food in the near future.
And I think that the low fertility rate of society is a process of self-redemption, inevitable and accidental coexistence.
It is as if the human society spontaneously corrects some kind of problem, although it is not positive and good, but this is the result of all things working together.
