Time goes by
The sun shines on the earth, standing in the reflection of Santaijie, I want to boil a pot of wine and talk to the ancients in the air. No matter what method the posterity uses, the Great Wall at the border will be stuck in the brain, and the mottled traces of the bricks and tiles will be replayed repeatedly. If you reach out and touch it, the depths of your chest will thump. I know that the ancestors worked hard and built the seemingly cold Great Wall and piers with blood and sweat. I can feel their weight and the temperature of the skin. The flames of war at…

The price of paranoia
Recently heard a high theory: people with good physics scores will be smarter and have stronger logical thinking ability. Taste it today, the heart is a different taste. Like many people, I also started studying physics in the second grade of junior high school. I was very interested in this course from the very beginning, and Zhang Jin, the teacher who taught us physics, gave very unique lectures.

I was full of thoughts along the way, thinking about how to reject my mother’s enthusiasm for dressing me up graciously. I was really…

Enlightenment of Bank Run Crisis in the United States
After the epidemic, the Federal Reserve released a lot of water, which led to a flood of liquidity. Silicon Valley Bank, which mainly serves technology companies, has seen a sharp increase in deposits of more than 110 billion US dollars.
