In recent weeks, I always see that the last two digits of the time are 44, and the temperature of the computer CPU and the battery capacity of the mobile phone are both 4. Is this a bad omen?

Never mind. The reason why you feel this way is because you are afraid of this number. Once it appears, you remember it, while other numbers appear, you don't care, so you can't remember it. This is called Murphy's theorem in psychology.
