In 2147 AD, on the far side of the moon, Guanghan City, China.
The most correct decision Shet ever made in his life was to leave the earth.
He made many wrong decisions - such as filling out "Astrophysics" as a college entrance examination application, such as rejecting the stable job with a monthly salary of 3,500 yuan after graduation, such as telling the other party on a blind date, "My hobby is to look up at the stars." But he thought it was right to leave the earth.
As for why it was correct, he still couldn't tell clearly. After all, he had only been on the moon for three days and was still fresh. When he discovers that there is no Wi-Fi on the back of the moon, this "correctness" may have to be redefined.
