The reason why Maiduo pie was renamed is because there are many fake Maiduo pies on the market. In order to distinguish the real Maiduo pie from other counterfeit products, the original brand of Maiduo pie is "Maiduo pie". "Multiple" upgraded to "Mei Duoqi". In addition, when registering a trademark, Liu Zhanhua, the founder of Maiduo Pie, discovered that the word "Maiduo" had already been registered. After many efforts failed, he decided to change the brand name to "Maiduoqi".
