What birthday present should I give my dry sister? Not too cheap.

Then send some generous gifts, such as silk scarves (cold weather, you can choose something suitable for your sister's temperament), scented tea, perfume, scented lamps (to relieve fatigue), watches and other common gifts.

You can also choose some gifts according to your stepsister's hobbies, habits and personality, such as beautiful ornaments such as bracelets and earrings, or some relatively new and exotic gifts, such as sunshine pots, luminous pillows, personalized flash drives and dumbbell alarm clocks.

I hope my answer can help you. ...
