Although the author looks very unreliable, he is actually telling the truth, he will be hospitalized tomorrow, and he will not see you for a long time.

Life is really impermanent, you can read this book with a good look, you can also encounter this strange thing of birth, old age, sickness and death, and I have been acting arbitrarily for more than 20 years, but suddenly I am terminally ill...

Anyway, if I haven't been back for a long time, you've forgotten about this book! Uh-huh!
