Little Sheep has been a very traditional hot pot restaurant from the beginning, and its service mode and concept are very traditional. With the development of the times, people now have higher demand, so Haidilao has grasped people's psychology, constantly innovated the service mode, made customers feel at home here, and made all aspects of service guarantee very in place and very humanized, so Haidilao is now a household name and getting better and better. On the other hand, Little Sheep began to expand wildly after becoming bigger and stronger, and even expanded overseas. Little Sheep should learn from McDonald's and KFC and become a global chain model. However, China people's food is not suitable for foreigners, so Little Sheep was bought by other companies only a few years after it was listed in the United States, and it failed. Little Sheep can learn from its heyday at the beginning to its dismal state today. No matter for a person or a company, we must constantly innovate and keep up with the trend in order to be invincible.
