 The annual numbers are in decline due to legislation and public education campaigns (see below).As there are many revellers during the Mid-Autumn Festival, the Hong Kong Police Force has previously paid little attention to wax boiling, and hence many local youths see the festival as a chance for "legal fire-setting".However, due to the amounts of leftover melted wax in public areas and the inherent danger of the practice, in 1990 the Hong Kong Government began issuing public announcements to citizens not to boil wax.
