Why do some chain hair salons openly recruit?

As we all know, the development of hair salons mainly depends on the cash flow of customers and the number of employees in the store. The entry threshold of the hair salon industry is relatively low and the mobility is relatively large. Some employees come in to study, and may set up another portal after learning. Therefore, there is a large turnover of personnel. In order to make up for the turnover of personnel, there is no restriction on recruiting people.
