I'm a little upside down, but my life is a little irregular, day and night upside down. That is to say, in the state of sleeping during the day and working at night, contrary to most people working during the day and sleeping at night, day and night are reversed. A little means that there are some, that is, the amount is not large or the degree is not deep, slightly, slightly. The inversion of day and night means the inversion of day and night, which means that life is not normal.
