This formula is concise and clear, highlighting the two key words "freedom" and "choice". First of all, people always have a strong curiosity and expectation for free things, which can easily arouse people's interest. Secondly, adding "as long as you choose" can stimulate people's subjective initiative and enthusiasm, and make people really want to participate in activities. In addition, if other interesting and creative elements can be properly added to the slogan, it will also increase the attraction of the event.
When carrying out activities, offering discounts or free experiences can really attract people's attention, but at the same time, it needs to be handled with caution to avoid using exaggerated or false propaganda means, otherwise it will affect the reputation and image.
