What plays a major role in this is the expansion behavior of acquisitions and reorganization. In 1997, Nestlé acquired Shanghai Fule, and Shanghai Merlin Zhengguanghe Group, which reshaped the "Guangming Brand" domestic cold drink brand, was listed in 1998. Yili merged with Italy's Perfetti in Shanghai and Tianbao in Jilin. It is precisely because of this Frequent expansion behavior has caused brand operators to build firewalls to keep "enemies" thousands of miles away.
