Holiday activities usually involve venues, personnel, equipment, weather backup and on-site security. The later the decision is made, the easier it is to affect the program design and execution preparation.
Large-scale festivals are usually concentrated on a few dates, and venues, personnel and equipment need to be coordinated in advance, and temporary determination will compress preparation time.
Themes such as Spring Festival, Mid-Autumn Festival, National Day, and New Year's Eve usually involve traditional patterns, city symbols, and blessing texts, which require flight-friendly design in advance.
Crowd density is high during holidays, and spectator areas, roads, security and emergency passages need to be confirmed earlier.
Formal plans will incorporate event location, weather windows, pattern complexity, viewing surfaces, on-site procedures and safety boundary confirmations.
