If the "employee profit" in the first phase of the 4.0 course makes me feel enlightened, then the "customer profit" in the second phase makes me know the importance of developing thinking. A month passed, and after the last class, I learned to give full play to the enthusiasm of employees, exhort, accompany and encourage employees to send out lists. The new employees were afraid to send out the list, but I stayed with them. When new employees receive their first customer, they become confident. Then I watched her win the second client and grow up little by little. If my family is talking about ideas, then I teach us to inherit our own ideas, and customer profits and employee profits are connected in series. Only when the thought reaches a high level can we consciously form the executive power, pass it on to employees and then spread it to customers. Only in this way can we let customers know about the service of the store and staff. If this channel is not established, the service of employees will be worthless. After eight years of industry baptism, I was so miserable that I wanted to give up and couldn't sleep at night. My family's 4.0 course really made me feel the truth, equality and respect of my family.
