Stationary point, the stable turning point after the second derivation, is just like my troubled life.
The first part of my life was given by my parents, so I was admitted to Imperial College. I wanted to study abroad. I must be a turtle engineering elite;
The second phase of my life began when my parents passed away, so I ended up living like this: reading half-baked books, working unskilled jobs, and occasionally cheating on royalties for my work.
Oh, by the way, I boarded a pirate ship by mistake and got into the "bad habit" of playing in a band that I can't get rid of.
Balak? Beethoven? Or Tchalfsky? ?
Sorry, I only play cheap and noisy electronic keyboards and that old cello with a broken sound box.
In this world, how can we not live well?
So what if you stay abroad? You just hang out in Chinese circles, wash dishes for foreigners, pick up Chinese horses, and then come back to pretend to be grandchildren, get married, have children, and so on. .
I don't even know how happy I am. Our family has a vast land and abundant resources. We don't lack anything. The moonlight in China is very round, isn't it?
