How to train all farm employees?

Players can train employees by consuming family fairy tale coins.

You can choose different courses to improve employees' attributes in different ranges. It should be pointed out that:

1. Only five-star employees can be trained, at most 10 times. Limited employees, constellation employees and employees already in the factory can't be trained.

2. The positions in the training center are family-oriented, and each person can only train 1 five-star employees at the same time.

3. After the training, there will be a cooling-off period of 8 hours, and the next round of training can only be carried out after the cooling-off period.
