Critics: officials prohibit setting off firecrackers in cities on the grounds that firecrackers hurt people and cause fires, rather than trying to find ways to seek advantages and avoid disadvantages, which implies conscious or unconscious cultural discrimination. Smoking causes illness or fire every year, which is much more common than that caused by fireworks. Why can't we help it?. Banning fireworks not only implies cultural discrimination, but also removes the last festive atmosphere of the Spring Festival.
The statement 'Customs that set off the festive atmosphere, such as posting Spring Festival couplets, offering sacrifices to ancestors and welcoming the God of Wealth have disappeared during the Spring Festival in the city' is the hypothesis on which the critic's conclusion depends.
