My name is Wang Dachui, a retail investor. I only have 1,000 yuan a month for living expenses in college. I am really poor. My underwear has faded, but I can still wear it, but it feels a little itchy sometimes. Today, my roommate and I pooled 300U together. I made money today, so each of me, a shareholder, will get a new pair of underwear. It must be the same green color, because I buy when the price goes up and sell when the price goes down.
