Female protagonist, whether a child or a grandmother-aged woman, and no male lead. Some kind of golden finger, like a pocket dimension, is fine, but it shouldn't get too absurd, either at the beginning or throughout. No being doted on by everyone, no Heavenly Dao, and no lucky carp! Also, don't make the protagonist or any important supporting characters come from a super-powerful background! There seem to be so few stories like this.
