How to organize an exclusive employee birthday party?

First of all, let me introduce that our company's birthday party is held according to the constellation. I will prepare different themes for different constellations. The first point of holding activities is also necessary-to set off the atmosphere. Let employees clearly understand the theme of this activity at first sight and easily switch their mood to this theme. So how to set off the atmosphere? You can not only render the layout of the whole event, but also make a fuss about game gifts and birthday gifts. Show as many details as possible to let employees know that the company cares about them. For example, Leo likes to "show off" himself and let everyone know that he is a passionate lion, so the tone of the whole birthday party will be set on the costumes and items related to lions. Leo exclusive birthday cake, exclusive gift.
