The number 7 has always been quite special to me. I didn't expect that after all the twists and turns, I would end up intersecting with it again, and in a way I never could have imagined. Sometimes, watching the market's ups and downs, you really start to feel that these things follow a predetermined rhythm—initially turning 20,000 yuan into 150,000, a full 7.5 times increase. This dramatic turn of events sometimes makes you feel that fate is indeed playing a joke on you.
