Your sister Gu is secretly... trading cryptocurrencies behind her husband's back. She lost nearly 500,000. After being discovered by her husband, who I'll call Brother Gu (I don't know why she calls herself Sister Gu), I took over the account starting March 11. I'm currently cleaning up after Sister Gu; previously, the contracts were still losing tens of thousands of dollars, and the red was so glaring it hurt the eyes. After staying up late for two weeks, I finally turned it green for Sister Gu, and it's finally comfortable.
