There are two aspects to this problem: if you have a fitness business license, when you give fitness training to employees of a certain unit, or cooperate with qualified institutions for training (including teaching), then the training contract signed with foreign countries is valid. However, if your unit has not obtained the training qualification granted by the labor department for the time being, but has started the external enrollment training, then the signed contract will have validity problems. However, if it is not a large-scale enrollment training, it can be carried out in the form of personal training with students, no problem.

As long as it is within the business scope.
