Alas, why am I useless like this, aren't I just a little tired? Why is my body so fragile, I want to sleep with my eyes open, I really hate myself!

Ladies and gentlemen, you say how good it would be if people could not know how tired they were!

I still remember what Marie Curie said, how nice it would be if you could do your own research freely in a free country!

I'm in a free country now, but it's a pity! The burden of life can sometimes really make people vomit blood!

I'm afraid I can't update it today!

Come on! Tomorrow I will be even better, and one day I will be able to do what I love wholeheartedly!

Good night, I wish you all good night, everyone has good dreams and can make their dreams come true! (To be continued......)
