I agree to use your head under the dormitory! Put a pattern of flowers and candles, sing a birthday song downstairs and bring a bunch of chocolates (or other snacks your girlfriend likes).

Ask a few friends to hold cameras, flashing lights below, and mobilize onlookers to wave their mobile phones as light sticks. That scene is also quite spectacular!

If you have the energy, and the male and female dormitories in your school are opposite, then mobilize all the boys to create a love for you by lighting the lights at night! But it's too difficult. It is not easy for you to get all the boys to cooperate with you. )
